摘要
低山丘陵地区高速公路深开挖路堑边坡易发生滑坡,滑坡治理设计参数用实验方法不易获得。本文以某高速公路深开挖路堑边坡为例,利用数值模拟软件Geoslope,根据极限平衡法,采用不同本构模型进行路堑边坡设计参数反演,并对所得到的参数进行灵敏度分析。结果表明:黏性土的黏聚力对边坡安全稳定性影响最大。
Low mountain-hill region of freeway deep excavation is prone to landslides, and landslide control design parameters is difficult to be gotten used test methods. Taking a deep open Geo--SLOPE freeway cutting slope excavation for example, by using numerical simulation software Geoslope, based on the limit equilibrium method, constitutive models using a variety of cutting slope design parameters inversion, and the parameters of the model are obtained. The results show that the safety and stability factors of cohesive are most affected by the slope of cohesive soil slope.
