压实粘性填土挡土墙土压力离心模型试验

Centrifuge Model Tests on Lateral Pressure on Walls Retaining Compacted Clayey Backfill

笔者利用自制的一套位移控制液压装置做了11组位移可控式压实粘性填土档土墙土压力的离心模型试验。本文对粘性填土的裂缝深度及其影响因素、土压力的大小、分布及其与墙体位移的关系等问题进行了试验分析。

By the means of a hydraulic displacement control mechanism made by the authors, centrifuge model tests on lateral pressure of wails retaining compacted clayey backfill, which displacement can be controlled, have been conducted. Depth of crack and its effective factors, relations of magnitude and distribution of lateral pressure versus wall displacement are discussed.
