摘　　要：抗震设计是挡土墙设计中需着重考虑的环节,柔性挡墙在抗震方面比刚性挡墙更有优势。本文针对一种新型的柔性挡墙—自嵌式挡墙进行研究,通过对三种自嵌式挡墙模型进行试验,结果表明自嵌式挡土墙经合理设计完全能抵抗大的地震动载,适合在地震区推广应用。另根据朗金理论破裂面,给出了自嵌式挡土墙在地震工况下的土压力理论公式,并与大量实验研究结果相吻合。Seismic design is a crucial aspect to consider in the design of retaining walls,and flexible retaining walls have more advantages in seismic resistance than rigid retaining walls.This article focuses on a new type of flexible retaining wall-self embedded retaining wall.Through experiments on three models of self embedded retaining walls,the results show that self embedded retaining walls can fully resist large seismic loads through reasonable design and are suitable for promotion and application in earthquake prone areas.According to Rankine's theory of rupture surface,a theoretical formula for soil pressure of self embedded retaining walls under earthquake conditions is provided,which is consistent with a large number of experimental research results.
