Frost heaving damage of water conservancy project is widespread. Water migration is the principal factor, which influences the frost heaving characteristics of soil. In order to research the failure problems of hydraulic soil slope in dark seasonal frozen soil region, the layered water content is observed. It is researched that the rule of water migration characteristics. That offers theoretical basis and reference for construction of water conservancy project and guidance for engineering practice. © (2013) Trans Tech Publications, Switzerland.

Frost heaving damage of water conservancy project is widespread. In order to research the failure problems of hydraulic soil slope in dark seasonal frozen soil region, laboratory model test is carried out combined with field test section practical situation, which is the prototype of this model test. It is researched that the rule of frost heave parameters variation and the damage of soil slope during freeze-thaw cycling. That offers theoretical basis and reference for construction of water conservancy project, which will mitigate the effect and damage of freeze-thaw on hydraulic soil slope stability. © (2013) Trans Tech Publications, Switzerland.

In order to solve the rainfall simulator single control operation currently used in the experiment of soil erosion. A mobile rainfall simulator was designed. The device adopts a rainfall simulator and Longmen mobile support integration mode, which is controllable and mobile and easy to move. The results show that the equipment is advanced in technology, stable performance, flexible movement, rainfall uniformity high, effective rainfall area is 1.5×4.5m with rainfall intensity ranging from 9.5 to 100mm/h. and to a greater extent meets the needs of rainfall simulation. This rainfall simulator can be used in indoor and outdoor experiment of soil erosion in different slope, which improves the efficiency of utilization of rainfall simulator. © (2013) Trans Tech Publications, Switzerland.

The digital image displacement measurement technology and finite element data smooth were applied in the soil slope shaking table test. The displacement field and strain field were obtained from the whole vibration process. And the seismic failure mode and failure mechanism were discussed as well. The results show the deformation of soil slope increases gradually; there is shear failure from slope middle to toe and tension-shear failure at the top of slope; there forms deep arc-shaped slip surface when the slope model fails. The generalized curvature of displacement time-history curve is used to judge whether the slope seismic failure is feasible.

A large number of soil and water conservation programs have been implemented on the Loess Plateau of China since the 1950s. To comprehensively assess the merits and demerits of the conservation practices is of great importance in further supervising the conservation strategy for the Loess Plateau. This study calculates the impact factors of conservation practices on soil, water, and nutrients during the period 1954-2004 in the Nanxiaohegou Catchment, a representative catchment in the Loess Mesa Ravine Region of the Loess Plateau, China. Brief conclusions could be drawn as follows: (1) Soil erosion and nutrient loss had been greatly mitigated through various conservation practices. About half of the total transported water and 94.8 % of the total transported soil and nutrients, had been locally retained in the selected catchment. The soil retained from small watersheds do not only form large scale fertile farmland but also safeguard the Yellow River against overflow. (2) Check dam was the most appropriate conservation practice on the Loess Plateau. In the selected catchment, more than 90 % of the retained soil and water were accomplished by the dam farmland, although the dam farmland occupied only 2.3 % of the total area of all conservation measures. Retention abilities of the characteristic conservation practices were in the following order: dam farmland > terrace farmland > forest land and grassland. (3) The conservation practices were more powerful in retaining sediment than in reducing runoff from the Loess Plateau, and the negative effects of the conservation practices on reducing water to the Yellow River were relatively slight. © 2012 Springer Science+Business Media, LLC.

Heilongjiang Province is one principal grain production base in China, and under the background of water-saving and grain-increasing action, high efficiency water-saving irrigation schedules and requirements of corresponding equipment need to be solved urgently. As a result, the situation of completion of annual task, experience gained, existing problems and suggestions are analyzed since the project of water-saving and grain-increasing action has been implemented in the province. The results show that sprinkler irrigation technique is the major irrigation schedule for dry farmland in the pro-vince. It is predicted that the walking sprinkler and centered pivot irrigation sprinkler will become the major irrigation schedule gradually by 2020 from the walking sprinkler alone right now. It is estimated that 277 centered pivot irrigation sprinklers, 2734 walking sprinklers and 415 micro sprinkler irrigation units will be needed in six years from 2015 to 2020 in the province. ©, 2015, Editorial Department of Journal of Drainage and Irrigation Machinery Engineering.

Freeze-thaw action is a complex moisture-heat-mechanics interaction process, which has caused prevailing and severe damages to canals in seasonally frozen regions. Up to now, the detailed frost damage mechanism has not been well disclosed. To explore the freeze-thaw damage mechanism of the canal in cold regions, a numerical moisture-heat-mechanics model is established and corresponding computer program is written. Then, a representative canal in the northeast of China is taken as an example to simulate the freeze-thaw damage process. Meanwhile, the robustness of the numerical model and program is tested by some in situ data. Lastly, the numerical results show that there are dramatic water migration and redistribution in the seasonal freeze-thaw variation layer, causing repetitive frost heave and thaw settlement, and tension-compression stresses. Therefore, the strengths of soil are reduced after several freeze-thaw cycles. Further, the heavy denudation damage and downslope movement of the canal slope would be quite likely triggered in seasonally frozen regions. These zones should be monitored closely to ensure safe operation. As a preliminary study, the numerical model and results in this paper may be a reference for design, maintenance, and research on other canals in seasonally frozen regions. © 2014 Springer Science+Business Media Dordrecht.

This paper presents workability, compressive strength and microstructure for geopolymer pastes and mortars made of class C fly ash at mass ratios of water-to-fly ash from 0.30 to 0.35. Fluidity was in the range of 145-173 mm for pastes and 131-136 mm for mortars. The highest strengths of paste and mortar were 58 MPa and 85 MPa when they were cured at 70 °C for 24 h. In XRD patterns, unreacted quartz and some reacted product were observed. SEM examination indicated that reacted product has formed and covered the unreacted particles in the paste and mortar that were consistent with their high strength. © 2013 by the authors.

Through testing the creep characteristics of plastic geogrid under the temperature of 20°C, 10°C, 0°C and -20°C, we obtained the creep characteristics curve under the different temperature.In order to obtioning the creep regulations of plastic geogrid by freezing and thawing cycle, we made the plastic geogrid for10 times freezing and thawing cycle at -20°C - 20°C, the one which was tested under the temperature of 20°C until its deformation became stable. Conclusions: (1) The creep of the plastic geogrid under different temperatures is quite different, it is greatly influenced by temperature and the lower the temperature the smaller the creep value; freezing and thawing cycle have influence in creep characteristics,In the condition of freezing and thawing cycle,while the creep value get stable at the normal temperature, the creep value also increasing with the temperature getting high and decreasing with temperature getting low; (2) According to the creep regulations under low temperature and freezing and thawing cycle condition,we advance the counting method of impact factor of freezing and thawing cycle, DR and creep impact factor of low temperature FcR. © (2012) Trans Tech Publications, Switzerland.
