近年地震中的液化侧向扩展与岸坡滑塌

Lateral Spreading of Liquefaction and Slope Slide during Earthquakes in Recent Years

唐山地震与海城地震中液化引起的侧向扩展与岸坡塌滑造成严重震害,但未进行过专题研究。本文回顾了国内有关震害资料,对侧向扩展的机理、影响范围等进行探讨并分析了几个典型事例。供城乡规划、抗震设防及土动力学研究参考。

Sev ere damages were caused by lateral spreading and slope slide induced by liquefaction in the earthquakes of Tangshan and Haicheng, but no monographic study has been conducted. Relevant domestic information on earthquake disasters are reviewed herein. The mechanism of lateral spreading, its extent of influence and so forth are discussed and several typical cases are analyzed, which are feasible for reference to the study of urban and rural planning, aseismic protection and soil dynamics.
