| 摘 要： | 滑带土是滑坡土体的重要组成部分,滑带土的强度特性是分析滑坡稳定性重要前提。边坡滑带土的强度特性受多种因素的影响,正确分析各种影响因素对选择合理的强度特性指标具有重要意义。本文通过某潜在土层滑移带的现场取样,首先采用室内试验得到滑带土的物理力学性质,然后分析应力历史和含水率对滑带土抗剪强度的影响。经过分析得到滑带土的应力-应变关系具有应变硬化特征;土样的抗剪强度指标值随着先期固结压力增大而增大;含水率增大会导致土样的抗剪强度降低。

| Abstract: | The sliding soil is a very important part of the landslide.The strength properties of sliding soil is an important prerequisite for the stability analysis of landslide.Slope sliding soil strength properties are affected by many factors.The reasonable analysis of various factors’ effect on the strength properties is very important to parameters selection.In this paper,with a potential slip-site soil sampling,laboratory tests were carried out to see the impact of stress history and moisture content on shearing strength of the sliding soil.It is shown that the shearing strength of sliding soil increases with the increment of preconsolidation pressure and decreases with the increment of moisture content. |
