摘要
边坡稳定分析中,目前广泛使用的极限平衡法在处理三维稳定问题时存在许多缺陷,而强度折减法能更好地处理三维问题。以广西某工程为例,采用三维有限元法模拟实际边坡,分析其在不同工况下的稳定性。研究结果表明,强度折减法在进行三维边坡稳定分析时是可靠、合理的。
The limit equilibrium method is widely used in slope stability analysis, but there are many defects when it is adopted in three dimensional stability problems. However, the strength reduction method can bitterly solved these problems. Taking a project in Guangxi as example, the actual fiver slope is simulated by three-dimensional finite element method, and its stabilities under different operation conditions are analyzed. The results show that the application of strength reduction method in three-dimensional slope stability analysis is reliable and feasible.
