摘要
在地质环境较为脆弱的地区修建高速公路,经常出现路堑高边坡滑坡灾害,本文以鄂西高速公路路堑边坡中典型的土石混杂高边坡望城坡为研究对象,使用FLAC3D软件对望城坡边坡不同工况进行数值建模分析,通过对数值模拟结果和边坡具体破坏模式对比分析,深入研究了土石混杂高边坡的变形破坏过程及其稳定性,揭示了土石混合边坡的变形破坏机制,并为同类型边坡施工和设计提供了科学的理论依据。
In the ecologically fragile area,there are some high cutting slope landslips during the highway construction.Wangcheng slope is one of the typical high cut slopes in western Hubei highway.The FLAC3 Dis used to build the numerical model of Wangcheng slope in different conditions.Through comparing the numerical analysis results with the practical failure modes,the soil-rock high slopes deformation process and stability are further studied,and the soil-rock slope deformation and failure mechanism are revealed.Finally,the scientific theoretical calculation to the similar slopes＇ design and construction are provided.
