| 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,并通过简单算例阐明了莫尔-库仑公式及Barton经验公式在岩质边坡稳定性分析中的差异.

| Abstract: | 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. |
