| 摘 要： | 在传统的边坡安全性分析中 ,人们都不考虑开挖扰动和基质吸力的影响。笔者通过试验 ,研究了开挖扰动对土体工程性质的影响 ,并且建立了考虑开挖扰动和基质吸力影响的基坑边坡安全性分析模型 ,还给出了计算实例。研究结果表明 ,开挖扰动和基质吸力对边坡安全系数有较大的影响。

| Abstract: | The influences of excavation disturbance and matrix
suction are not considere d in the analysis of traditional slope stability. By experiment,
the engineering properties of soils influenced by excavation disturbance are discussed.
The cal culation model considering the influences of excavation disturbance and matrix s
uction has been established. The calculation example is shown at the end. The re sult
indicates that excavation disturbances and matrix suction could exert an ob vious
influence on the slope safety factor. |
