摘要
由于岩质边坡的失稳几乎都是沿着结构面发生的 ,而岩体结构面的抗剪性能并不完全满足莫尔—库仑准则 ,因此在岩质边坡的稳定性分析中采用莫尔—库仑准则会带来较大误差 .本文用Barton经验公式代替莫尔—库仑准则进行岩质边坡的极限平衡稳定性分析 ,以更好地反映岩体结构面的抗剪性能 。
Since the stability failure of rock slopes happens almost along joints, while the shearing characteristic of joints does not fully accord with Mohr_Coulomb's criteria, using Mohr_Coulomb criteria in stability analysis for rock slopes will result in large error. This paper replaces Mohr_Coulomb's criteria with Barton's empirical formula in limit equilibrium analysis for rock slopes in order to properly show the shearing characteristic of joints, and illustrates the difference between using of Mohr_Coulomb's criteria and Barton's empirical formula in stability analysis for rock slops with a simple example.
