摘要
考虑到边坡稳定性分析的随机性与全局性,通过收 集若干个边坡稳定性方面的实例,采用统计学的最大似然估 计方法以及一般多元回归方法估算边坡稳定性的安全系数, 建立边坡稳定性的估计模型。然后通过对实际边坡的安全 系数进行估计,并与传统的监测数据进行对比分析,结果表 明,两种估算方法估计的结果与实际情况较为接近。
Considering the randomness of stability analysis of slope and the need of its global analysis ,based on the collected example data of the slope stability analyses, the safety coefficients have been calculated by the maximum likelihood estimation and the general multivariate regression, and the estimation model of slope stability has been established. Then, the safety coefficients of practical slopes have been estimated, and compared with the data obtained from convention monitoring. The results shows that the safety coefficients calculated by the above two method are approach to the monitored results.
