摘要
文中以白磷岩至沿渡河公路石马山(K12+853.00~K12+950.00)段路基边坡为例。分别采用二维极限平衡法和三维数值模拟法,从岩土体内部变形和应力的角度并结合安全系数大小分析评价其稳定性。多种分析方法相互印证表明:边坡存在失稳风险,在不确定的诱发因素作用下将会发生滑塌地质灾害。建议对此段路基予以改造加固,以免造成灾难。
This paper,taking the Cutting slope of the Shimashan Section(K12+853.00~K12+950.00)of Bailinyan to Yanduhe Highway as a case study,analyzes and evaluates the stability by using 2D limit equilibrium and three-dimensional numerical simulation method from different perspectives,including deformation,stress in rock and soil mass and the safety factor.A variety of analytical methods verify that the slope has the risk of instability and the landslide geological hazard may occur under the influence of the uncertain inducing factors.It is suggested that the subgrade be modified and reinforced to avoid disaster.
