| 摘 要： | 本文首次将模糊测度（ｆｕｚｚｙｍｅａｓｕｒｅ）理论用于分析岩土边坡稳定问题。根据模糊测度理论，针对实际边坡工程问题，建立了具有普遍意义的理论分析模型，并给出了具体的数值方法。计算分析结果表明，理论值与实际情况相一致。同时也证实了模糊测度模型比已有的经典分析方法具有明显的优越性。本文方法适用于分析土质边坡及节理裂隙发育的岩质边坡等各类边坡稳定问题。

| Abstract: | Because of the complex nature of rock (soil)mass in open -- pit mines, it is difficult to accurately measurevarious factors which have great effect on the slope stability. Based on results of the statistical analysis of a largeamount of measured data in geotechnical engineering and civil engineering, the fundamental fuzzy models of rock(soil) slope stability are established by using the theory of fuzzy measures. To calculate the rock(soil) mass stability,the rock (soil) mass is regarded as a macroscopically homogeneous and isotropic medium, and thus a new numericalmethod for analysing the fuzzy measure of rock (soil) slopes is derived. The practical calculation shows that themethod can be applied to analyze the problems of the rock (soil) mechanics. |
