压实粘性填土挡土墙土压力的离心模型试验

Centrifuge Model Tests for the Lateral Pressure of Walls Retaining Compacted Soil

作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挡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 means of a self-made hydraulic displacement control mechanism ,some centrifuge model tests for the lateral pressure of walls retaining compacted soil,of which the displacement can be controlled ,have been performed. Problems such as the relations between the magnitude and distribution of lateral pressure and wall displacement are discussed in this paper.
