摘要
为提高排土场边坡稳定性等级评价的客观性和准确性,运用组合权重和改进逼近理想解排序法建立排土场边坡稳定性评价模型。首先选取坡高、坡度、堆积台阶数等9个主要影响因素构建排土场边坡稳定性评价指标体系,再采用层次分析法和基于指标相关性的指标权重确定法获取指标的最优权重,结合灰色关联系数改进逼近理想解排序法建立边坡稳定性评价模型。以乌龙泉排土场边坡为研究对象,完成9个测点的稳定性评价,结果表明:所提评价指标权重与评价模型获得的评价准确率优于对比方法,在排土场边坡稳定性评价中适用性高,具有工程指导意义。
To improve the objectivity and accuracy of dump slope stability grade evaluation,the slope stability evaluation model of dump slope was established by using the combined weights and an improved technique for order preference by similarity to an ideal solution(TOPSIS).Firstly,nine main influencing factors including slope height,slope and number of stacked steps were selected to construct the slope stability evaluation index system of the dump slope,then the analytic hierarchy process and the criteria importance through intercriteria correlation were used to obtain the optimal weights of the indexes,and the slope stability evaluation model was established by combining the gray correlation coefficients to improve the TOPSIS.Finally,taking the dump slope of Wulongquan as a research object,the stability evaluation of nine measurement points was completed.The results show that the evaluation accuracy obtained by the proposed evaluation index weights and evaluation model is better than that of the method in comparison.It has high applicability in the slope stability evaluation of the dump slope,which is useful to guide engineering.
