摘要

基于Morgenstern-Price条分法和Monte-Carlo数值模拟法,将地震系数视为随机变量,运用可靠度理论分析了地震系数的分布特征对土坡稳定性的影响和最危险滑面的变化规律。结果表明,水平地震系数比竖向地震系数对土坡安全性的影响大,地震系数均值较其变异系数对土坡稳定性和最危险滑面形状的影响更显著,可为类似研究提供借鉴。
Earthquake coefficient being regarded as random variable,based on the Morgenstern Price slices method and Monte Carlo numerical simulation,the influences of the distribution characteristics of earthquake coefficient on soil slope stability and the variation rules of the most dangerous slip surface are studied with the reliability theory.The calculation results show that the influences on soil slope safety of the horizontal earthquake coefficient are more significant than that of the vertical earthquake coefficient,and the mean value of earthquake coefficient has more significant impact than its variation coefficient on both the soil slope stability and the shape variation of the most dangerous slip surface,which can be referenced for the similar research.
