摘要
基于强度折减理论,以ABAQUS有限元软件为平台,以数值计算不收敛为边坡失稳的判据,对云南富宁港岸坡安全系数随岩体参数的变化进行了数值模拟,结果表明:随着岩体强度的变化,岸坡稳定性由安全状态到临界状态,最后变为不安全状态;周期性浸泡对岩体力学参数的劣化会导致岸坡稳定性降低。
Based on intensity reduction theory,the numerical simulation was processed with the finite element method and ABAQUS analysis software.With the non-convergence of numerical calculation for the slope stability criterion,it took bank project of Funing Port of Yunnan Province as an example.The results show that with the change of rock mass intensity,the stability of banks is from safe status to critical status and finally becomes instable.The periodic change of soak induces the reduction of stability.
