Analysis of the Active Earth Pressure Under Different Displacement Modes of the Rigid Retaining Wall

摘要

Earth pressure is the main load acting on the foundation pit support system, which is the result of the interaction between soil and retaining structure. Based on the different displacement modes of the retaining wall under the active earth pressure condition, the finite element method is used to analyze the characteristics and variation of the active earth pressure distribution of the retaining wall in various displacement modes. The distribution of earth pressure is essentially linear until the soil is destroyed under T mode, the upper part soil reach the active earth pressure state first under RBT mode and the lower part soil reach the active earth pressure state first. In RBT and RTT modes, when n is large, the state of the earth pressure distribution at each stage is close to the state when the retaining wall translates.
