Deep soil mixing (DSM) to form in-ground shear walls has been used to remediate against the potential effects of earthquakeinduced liquefaction on many projects. A grid pattern of soil-cement walls act as a confined shear box, which can provide additional shear stiffness and strength for sites to withstand liquefaction. Current design practice for DSM grids commonly relies on the strain compatibility assumption, where the DSM walls and confined soil are assumed to experience the same shear strain. In this paper, the distributions of shear stresses and strains in liquefiable soil deposits treated with DSM grids are investigated using three-dimensional linear elastic finite-element analyses of unit cells. Parametric analyses are performed for a range of geometries, relative stiffness ratios, and dynamic loadings. These linear elastic results provide a baseline against which future nonlinear modeling results can be compared, but they are also sufficient for demonstrating that shear stress reductions are less than predicted by the assumption of shear strain compatibility. Modifications to the shear strain compatibility equation are presented, which improve its agreementwith the results of these analyses. © 2013 American Society of Civil Engineers.

The Clean Rivers Project is DC Water's ongoing program to reduce combined sewer overflows into the District of Columbia's waterways; being the Anacostia and Potomac Rivers and Rock Creek. The Project is a massive infrastructure improvement designed to capture and clean water during heavy rainfalls before it ever reaches the public waterways. To create the massive underground structures that form the solution to combined sewer overflows (CSOs), tunnel boring machines are being used to excavate tunnels more than 100 feet underground. Known as the Blue Plains Tunnel, this first section of tunnel is a 4-mile reach of the 13-mile Anacostia River Tunnel, stretching from the blue plains waste water treatment plant, to the Main Pumping Station in downtown, Washington, D.C. Along the route of the Blue Plains Tunnel is the largest advanced wastewater treatment plant in the world, the TBM launch shaft, retrieval shaft, several drop shafts (around which pumping stations are to be constructed), and numerous diversion sewers and ancillary structures to complete the massive CSO infrastructure system. At each of these locations, various forms of ground modification/ground improvement were performed, including independent SOE systems, support for micro-tunneling operations, ground-water control, utility protection, and settlement protection. This paper discusses the challenges and solutions for this specialty work. © ASCE.

The presence of hydro-collapsible soils beneath the proposed Erie Police Station project site led to the successful combination of two ground modification techniques. Normally in the presence of up to 30 ft (9 m) of hydro-collapsible soils, the soils are either over excavated and replaced, or the structure is supported by a deep foundation system. A collaboration between Hayward Baker Inc. (HBI) and GROUND Engineering Consultants (GROUND) resulted in an alternative two step ground modification process. The first step consisted of water injection to pre-collapse, "treat," the soils to a depth approximately above "perched" water levels, at about 18 ft (5.5 m). Consolidation tests were subsequently conducted on treated soils obtained from across the site to evaluate the effectiveness of the treatment process. In the second step, stone columns were installed to increase the bearing capacity at spread and column footing locations. The combination of these techniques provided the client with a sufficient foundation design that was cheaper and faster to construct when compared to conventional over-excavation and replacement or deep foundation system options.

Mass stabilization by dry soil mixing (DSM) is a ground modification technique that involves pneumatically injecting and mechanically mixing dry binder powder (Portland cement or a blend) with in situ soils. This produces a soilcrete mass that has higher strength and lower compressibility than the original soil. DSM by Mass Stabilization is ideally suited for loose or soft soils having high natural moisture content, including organic soils, located within 7 m or less of working grade. During the design process, the required unconfined compressive strength and elastic modulus of the soilcrete are determined based on the magnitude of the loads that are being supported and the amount of settlement that is acceptable. DSM was completed on several soft soil sites at Port Everglades, Florida. A total of fifteen new petroleum storage tanks at three new tank farms, for three different owners, were constructed on standard ring wall foundations after the highly organic in situ soils were improved by mass DSM. The above ground storage tank sizes ranged from 12.19 m to 18.29 m tall, and from 12.19 m to 42.7 m in diameter. Soilcrete material quality was verified during construction by coring and by penetration testing. After the tanks were constructed, full-scale hydrostatic load tests were performed to verify that the tank settlements were within acceptable limits. The load-settlement responses of the tanks were better than anticipated, and easily satisfied the stringent performance criteria. The DSM design procedure and the data from the load testing are presented and discussed. © ASCE.

For decades compaction grouting and low mobility grouting (LMG) have been utilized extensively to stabilize structures, remediate variable soil types, enhance bearing capacity, cut off water, and relevel structures and roadways throughout the Rocky Mountains and beyond. The popularity and diversity of this geotechnical solution will be demonstrated through a multitude of case histories in cohesive, granular, collapsible, and voided ground conditions as well as in wet and dry environments. Though the fundamentals of the process have primarily remained the same since inception, advancements have been made in the form of innovative applications, data acquisition systems, and computer modeling to assist engineers and owners in assessing unique and challenging geotechnical sites and conditions.

The United States Army Corps of Engineers (USACE) manages the Houston Ship Channel dredging operations, required to maintain the flow of barges within the ship channel. Disposing of the dredge materials requires the creation of disposal islands throughout the channel. A levee surrounds each island to contain the dredge material during a storm event, preventing spillage into the ship channel, which would inhibit movement of barges through the channel and shutting down all commerce. In 2009, the USACE led a project to increase the existing levee heights at a number of the islands to increase dredge storage capacity, including the Lost Lake Dredge Material Placement Area (DMPA). Lost Lake's current levee elevation of EL. +8.2 m (27.0 ft) required a change in grade to EL. +10.9 m (36.0 ft) an increase of 2.7 m (9 ft). During construction, the levee failed several times over a 640.0 m (2,100 ft) stretch. This portion of the levee had a history of failure. The poor soils beneath the levee footprint in this area required stabilization prior to increasing the elevation. The design-build team designed a deep soil mix (DSM) ground improvement program, which included shear panels with overlapping dry soil mix columns, to improve soil beneath the levee with a combined shear strength of 1,000 psf. The panels were constructed at varying depths and lengths depending on the strength of the in situ soil, and were perpendicular to the levee. Dry soil mixing proved to be challenging and required very precise planning and execution because it was located on an island, but also proved to be the most cost effective method due to the remote nature of the work. The levee now performs as designed since raising its elevation to EL. +10.9 m (36.0 ft) after ground improvement.

The William Eckhardt Research Center, a 25,500 square meter (275,000 square foot) building, was constructed on the University of Chicago campus. The structure features five floors above grade, a basement and a sub-basement. The proposed depth of excavation to construct the basement varied between 15 and 16.5 meters (49 and 54 feet). A diaphragm wall was selected as the earth retention system and permanent foundation wall due to its cost effectiveness and ability to minimize groundwater infiltration into the facility after construction. The urban, congested nature of the project location presented many design and construction challenges. The research center is located in the heart of the University of Chicago campus next to two active streets containing many utilities critical to the operation of the University, as well as two active research facilities, which house experiments that are highly sensitive to vibrations. To address these various challenges, multiple techniques were required to support each side of the excavation, including tiebacks, internal bracing, and micropile mid-span supports. The neighboring University research structures required underpinning which was accomplished using a combination of micropiles, tie downs, and jet grouting. Inclinometers and settlement points were installed and monitored throughout the braced excavation construction. The data collected showed negligible settlements, and horizontal deflections of less than 2.1 centimeters (0.8 inches) across the profile of the wall. © ASCE.
