基于属性数学的土质边坡稳定性评价模型及应用

Model for comprehensive evaluation of soil slope stability based on indeterminacy mathematics and its application

鉴于边坡稳定的不确定性,引入属性数学和联系数学方法评价土质边坡稳定性。提出了属性数学识别模型。应用属性权系数法确定评价指标的权重,根据单指标的属性测度值与多指标的综合属性测度值,利用联系数识别边坡稳定性等级。计算结果表明,该方法与传统的安全系数法的结果基本相同,为评价土质边坡稳定性探索了一条新的途径。

Abstract： For the indeterminacy of the soil slope stability, the theory of attribute mathematics and connection mathematics are introduced to analyze the slope stability in this paper. An attribute mathematical recognition model is set up. The weights of the indices are determined by the attribute coefficient method, and the level is identified by using the connection number according to the attribute measure values of single index and multiple indices. The calculation result shows that the method and the safety factor method have the same results. This proposes a new method for evaluating the slop stability.
