| 摘 要： | 软土地基在地震作用下,将会产生变形,包括周期性可恢复变形及不可恢复残余变形(永久变形),会造成土体震陷、构筑物失稳,特别是对于地下管道,常常引发灾害性事故,造成极大的经济损失.相对于周期性可恢复变形,残余变形对软土地基建筑物的使用和运营影响更大,加之由于软土本身具有高压缩性、低强度、高灵敏度等特性,软土地基的震陷问题也...

| Abstract: | The foundation instability is always a usual problem encountered by engineers.Under earthquake,soft soil foundation subsidence occurs,which induce hazards and economic loss,especially for underground pipelines.With high compressibility,low strength and high sensitivity of soft soil,earthquake subsidence is complicated.In this paper,research progress of soft soil earthquake subsidence about its reason,mechanism,influence factors and analysis methods is summarized. |
