材料强度非均匀性对土石混合体边坡稳定性的影响

土石混合体边坡是一种典型的非均质边坡,材料强度存在典型的非均匀性。为考虑材料变异性对土石混合体边坡稳定性的影响,采用Monte-Carlo算法研究材料非均匀性对边坡稳定性的影响。结果表明,在非均匀的土石混合体边坡中,随着材料变异系数的增加,边坡的安全系数逐渐降低。在边坡稳定性评估和加固过程中,应充分考虑材料强度的非均匀特性。

The slope of soil-rock mixture is a typical heterogeneous slope,and the material strength has typical inhomogeneity.In order to consider the influence of material variability on the stability of soil-rock mixture slope,the influence of material inhomogeneity on slope stability is studied by Monte Carlo method.The results show that in the non-uniform soil-rock mixture slope,the safety factor of the slope decreases gradually with the increase of the coefficient of variation of materials.The non-uniform characteristics of material strength should be fully considered in the process of slope stability evaluation and reinforcement.
