摘要
针对某工程实例,在降雨以及坡体随意堆弃工况下对弃方边坡的稳定性进行概念 分析,利用FLAC3D有限差分软件对该边坡稳定性以及边坡破坏滑动过程进行数值模拟,并 利用能量守恒法计算出该边坡滑动影响范围.结果表明:弃方堆积体边坡在天然状态下处于 临界稳定状态,在暴雨或连阴雨状态下处于不稳定状态,将会发生滑塌;北侧弃方堆积体 最大滑程为15.0 m,这将会威胁北侧弃方堆积体边坡坡脚桥墩安全.建议所有实际工程都应 分析随意堆弃边坡的稳定性.
Abstract
For a project example, the stability analysis of the slope stability is carried out under the conditions of rainfall and random dumping. The slope stability and slope failure sliding process are numerically simulated by FLAC3D finite difference software. The slope of the slope is calculated by the energy conservation method. The results show that the slope of the abandoned body is in a critical state under natural conditions, and it will be unstable under heavy rain or continuous rain. The maximum slip of the north side abandonment body is 15.0m. It will threaten the safety of the foot bridge piers on the slope side of the abandoned side of the north side. It is recommended that all actual projects should analyze the stability of the freely abandoned slope.
