摘要

提出采用灰色系统理论中的灰色关联分析方法对边坡稳定进行敏感性分析

通过建立起边坡的灰关联数据矩阵

并采用极差变化对数据矩阵进行无量纲化处理

可计算出敏感因子变化与边坡安全系数之间的灰关联系数和灰关联度

从而确定出边坡稳定的敏感因素。结合福建某边坡加固工程实例

针对土体容重、粘聚力、内摩擦角、地下水位、坡高、坡率等影响因素

对该边坡稳定性进行了单因素的敏感性分析。结果表明

土体的内摩擦角、粘聚力是影响该边坡稳定性的主要敏感性因素

进而提出了有针对性的边坡加固措施。

Abstract

Grey Correlation Method is employed to analyze the sensitivities of factors influencing slope stability.The matrix of correlation data is set up

the elements of which are then transformed to dimensionless parameters using top-difference transforming method.The grey correlative factors and grey correlative degrees between the influencing factors and the safety factor are computed

and the sensible factors influence slope stability are then determined.This method has been applied in a slope reinforcement project in Fujian province.The influencing factors such as unit weight

cohesion

internal friction angle

groundwater level

slope height as well as slope angle are considered.The sensitivity of slope stability is analyzed with the above-mentioned factors being taken as independent and dependent respectively.The result shows that internal friction angle and cohesion are the principal susceptive factors influencing the slope stability

on the basis of which effective reinforcement measures are put forward.
