【摘要】 水平地震作用沿墙高的分布、弱粘性土地震土压力、和挡墙体系考虑水的作用是挡土墙抗震研究中的三个重要问题。首先对其研究进展进行了简要总结。然后针对近年来大量涌现的新型、异型、轻型挡土墙的抗震研究现状进行了评述,包括现场地震调查、振动台及离心机试验、悬臂L型挡土墙、锚杆式及土钉式挡土墙、加筋土挡土墙和地下室挡墙。最后,指出了存在的问题和提出今后的研究方向。更多还原

【Abstract】 Lateral seismic action along the height of a retaining wall,seismic earth pressures on a retaining wall with cohesive backfill,and considering water effects on quay walls are three important aseismic questions.Firstly,the research advancement is discussed.Then,the advancement and evolutions of new type,complex type,and light type of retaining walls(RW) on nowadays,including field observation,shaking table test,centrifuge experiment,cantilever L-shaped RW,anchored RW,nailed RW,geogrid-reinforced soil RW and basement building wall are concisely reviewed.At the same time,concise remarks are made.Finally,existing problems are pointed out and the study problems,which need to be done in future,are suggested.更多还原
