Abstract：The issues of seepage analysis and design aspect of anti-seepage body in the design of deep foundation pit are concerned. It is shown that the importance of the seepage calculation of deep foundation pit should be focused on. The limits of current support standards for design and construction of deep foundation pit are pointed out. The basic requirements for foundation pit are provided and related countermeasures are also proposed. With three-dimensional finite difference method，the basic seepage characteristics of deep foundation pit are given；and the minimum embedded depth into soil(rock) of the underground continuous diaphragm wall is determined. The achieved results show that the proposed measures are feasible and they can provide references to similar engineering cases of deep foundation pits.
