Segmented numerical simulation method of reinforced soil retaining wall under long-term load
The long-term rigidity of geosynthetics is affected by factors such as loading time and stress-strain re-lationship.In this paper,the long-term rigidity expression obtained based on creep test is iterated with the stress and strain of the reinforcement to simulate the mechanical behavior change of the reinforcement in reinforced soil re-taining wall under long-term load,so as to obtain a set of simulation method that can better predict the long-term working performance change of the reinforced soil retaining wall.The finite element simulation is used to carry out the actual iterative calculation.By comparing with the non-segmented model data,it is concluded that reinforcement segmentation is more in line with the actual working state.The relevant results have provided reference for future simulation of the reinforced soil retaining wall under long-term load.
