摘要
液化层的减震作用一直是引人入胜的话题,但至今没有做过系统的研究。本文通过国内首次研制的多层剪切砂箱试验及一维有效应力分析对液化前后的应力、应变及减震机理等作了探讨。计算结果与实验结果在定性上是一致的,与通过宏观震害得到的认识也是相符的。
In this paper a series of experimental and analytic study have been conducted to clarify the mechanism of shake-reducing effect of liquefiable soil layers. The influence of the location and the thickness of liquefiable layers on the ground motion and so on. are shown in the paper.
