Abstract

As a new type of flexible retaining structure, reinforced soil retaining wall is widely used in civil engineering and highway engineering because of good seismic performance and economy. The residual displacement under seism is one of the most important parameters to evaluate the seismic performance of reinforced soil retaining wall. The related theoretical research is rare. Taking the pseudo-dynamic method and kinematic differential equation as the theoretical basis, considering the residual deformation under large magnitude, a theoretical method is proposed to calculate the residual displacement of reinforced soil retaining wall under seismic. The rationality and accuracy of the theoretical method is verified by centrifuge model test. The results would provide some reference for the performance design and damage evaluation of reinforced soil retaining wall.
