| 摘 要： | 利用随机有限元分析法,考虑边坡岩土体的非均质、不确定性,把岩土体的物理力学参数分别看作正态分布函数来研究水厂铁矿的稳定性,分别给出岩土层的参数取值,并给出计算中函数取值的分布概率及其对边坡应力应变场的影响程度;得到该铁矿的应力和位移分布特征和边坡大于最大位移值的失效概率及影响最大位移的敏感性因素,从概率方面给出边坡的稳定程度.

| Abstract: | Using FEM,and considering the heterosphere and indeterminacy of the rock mass,and physical mechanical parameters of rock(soil) mass are looked as functions.With SFEM the distribution of stresses and displacements and the failure probability beyond the maximal displacement and the factors influencing the maximal displacement can be obtained.The degree of slope stability can be achieved in the probability by SFEM. |
