Abstract A modified pseudo-dynamic approach was used for a reliability-based stability analysis of plane failure rock slopes. The Barton-Bandis nonlinear failure criterion and the limit equilibrium principle were adopted to account for the nonlinear characteristics of rock joint shear strength and safety factor of slope, respectively. The Monte Carlo simulation method was used to analyze the rock slopes. Comparisons of the present method to a numerical simulation and to a pseudo-static case, were implemented. The influence of different parameters and tension cracks on slope stability was analyzed. Results showed that the stability of the rock slope decreases with increasing rock unit weight, horizontal seismic coefficients and vertical seismic coefficients, and increases with increasing residual friction angle, joint roughness coefficient and joint compressive strength. The location of the tension crack has significant influence on the stability of rock slopes, while the influence of inclination of the tension crack is negligible.

基于 Barton-Bandis 破坏准则的岩石边坡可靠度分析和修正拟动力法

摘要 一种改进的拟动力方法被用于平面破坏岩质边坡的基于可靠性的稳定性分析。采用Barton-Bandis非线性破坏准则和极限平衡原理，分别考虑了岩体节理抗剪强度和边坡安全系数的非线性特征。采用蒙特卡罗模拟方法对岩石边坡进行分析。实现了本方法与数值模拟和伪静态情况的比较。分析了不同参数和张拉裂缝对边坡稳定性的影响。结果表明，岩石边坡的稳定性随着岩石单位重量、水平地震系数和垂直地震系数的增加而降低，随着残余摩擦角的增加而增加，接头粗糙度系数和接头抗压强度。拉裂缝的位置对岩质边坡的稳定性有显着影响，而拉裂缝的倾角影响则可以忽略不计。
