Department of Hydraulic Engineering, Tsinghua University, Beijing 100084, China ) Abstract: The calculation methods of earth pressure and water pressure on retaining structure in the conditions of hydrostatic pressure, steady seepage, excess pore water pressure, have been analyzed and summarized. Some examples have been given to explain the difference between the methods of separately or integrally estimating water and earth pressures on retaining wall and the effects of seepage and excess pore water pressure on total pressure on retaining structure. Also the critical state analysis of stability of retaining structure has been emphasized Key words: retaining structure; earth pressure; water pressure; seepage; excess pore water pressure; critical state 1 前 言 力。首先考虑静水压力作用下，挡土结构上土压力 和水压力的计算。
