This paper introduces a coastal structure design to protect a reclamation site, which will be fixed at a level of +8 m above the chart datum. A jetty will be also used for loading and unloading of materials from the plant that will be developed on the nearby reclamation site. From the given site contours and water depth data, the bottom slope of the sandy foreshore can be determined. In order to design the coastal structure, the wave climate must be considered and analyzed in priority. For the vertical breakwater to be located on the other side of the berth jetty, the required base and height was determined. In addition, the seawalls for the reclamation platform were analyzed at different water depths. © (2014) Trans Tech Publications, Switzerland.

The combined method of piles and anchor cables is practicable in deep excavations. By using this method, the deformation can be controlled, the working space can be provided for pile foundation, and the project cost can be saved. Based on the excavation of Hanguo Commercial Center in Shenzhen, the factors for the combined method of piles and anchor cables are investigated. According to the monitoring data, the deformation rules of piles and the bearing force on bracings are analyzed. Further discussion and researches about caculating interior bracings especially the circular inner bracings are carried out.

Using the impact holing method in reclamation areas with thick silt-rock fill layer will cause several consequences such as large disturbance in silt, reducing pile hole, large filling coefficient of concrete and so on, and it will badly affect the high-pressure jet grouting water-resisting curtain construction between the piles. Through comprehensive analysis of the geological conditions, the following construction technology is proposed: firstly, using vibratory hammer to put the long steel casing into the upper part silt-rock fill layer, and then using the grab-type drill to grab the rock in the steel casing; secondly, using rotary drilling hole below the steel casing. By means of this kind of supporting construction technology, the stability of hole wall, fast formation of hole, less mud and low cost to implement the green construction are ensured.

Though the wide applications of jacked pile in engineering in Shenyang district, the problem is also exist in engineering for the capacity of the jacked pile is hard to account. The relationship between the standard penetration test and the ultimate vertical bearing capacity of jacked pile is established in this paper; also an empirical formula is put forward for calculating the ultimate vertical bearing capacity of the jacked pile in this district with blow count of standard penetration test (SPT). The engineering examples indicated that the empirical formula is feasible because the calculating bearing capacity of the silent pipe pile is coincided with the static load tests. The calculated results satisfy the engineering requirement and t can be concluded that the method is also convenient to choose the diameter and length of the pile during the initial stage of design. © (2011) Trans Tech Publications.
