Study of Stress Distribution Characteristics of Reinforced Earth Retaining Walls under Cyclic Loading

The stress-distribution angle is an important parameter for the design of retaining walls and foundation beds has a non-negligible role in rationality engineering design. There lack research on stress distribution reinforced earth-retaining under cyclic loading. In order to study characteristics geogrid-reinforced soil-retaining (GRSW) loading, GRSW different number load cycles were analyzed by field tests, effects length reinforcement, friction coefficient reinforcement–soil interface modulus reinforcement numerical simulation. results show that, with increase cycles, vertical dynamic earth pressure shows noticeable decreasing trend from high low along wall height. increases first then decreases reinforcement. When more than 100,000, does not change much, upper part remains at 35~79°, middle 47~68°. influence depth about 1.13 times interfacial soil superior GRSW, followed
