摘要

提出了一种确定离心模型试验过程中边坡的应力和位移场及其变化过程的方法。基于物理测量与数值模拟相结合的思路，首先采用离心场非接触位移测量技术测量出边坡的位移场；然后通过数值模拟和反演分析等途径算出边坡的应力场。该方法已成功用于多个边坡离心模型试验中的应力位移场的确定，表明了该方法可以较好地得出离心模型试验过程中边坡的应力和位移场。边坡离心模型试验结果表明，边坡的破坏过程与应变局部化和应力集中的过程有着密切联系。

Abstract

A new method is presented to capture the stress and the displacement fields of a slope in centrifuge model test process based on the scheme with the combination of physical measurement and numerical analysis. The displacement field is measured by using non-contact displacement measuring system on the basis of image analysis in centrifuge model test. Consequently

the stress field is obtained by using numerical simulation with back analysis. Such a method has been used for several centrifuge model tests. It has been confirmed to obtain the stress and the displacement fields of a slope in centrifuge model test process reasonably. The test results show that the progressive failure of a slope is dependent significantly on the process of the strain localization and stress concentration.
