The research for the numerical simulation technotloy of high-pressure groundwater sealing grouting;

Through classification and summary of decompression design for foundation pit construction, the steps and requirements of the design are provided for foundation pit construction in areas with high water table, including the normal operation and precautions so as to achieve the required construction quality and lower the engineering cost.

Prevention and control of ground water surge with high pressure and large flow for construction of auxiliary tunnel of Jinping Hydropower Station;

This paper gives methods about borrowing non-homogeneous soil in high water level and stabilizing the soil.

In high water level condition in seasonal frozen soil region,the aggregative indexes of the large channel panels are higher because the foundation soil has high moisture content,strong frost heave and powerful ice thrust.
