摘要
膨胀土边坡破坏具有浅层性、裂隙性和牵引性,对于膨胀土地区的高速公路,在降雨作用下,膨胀力对边坡稳定起控制作用。基于简布极限平衡法的思路和方法,对膨胀土边坡稳定性进行了分析,并推出了安全系数的表达式。
Slope; failure of expansive soil is characterized by fissure inducement at shallow. Slope stability along the expressway lying in expansive soil region is controlled by swelling pressure. The slope stability of expansive soil is estimated and an expression of the coefficient of safety is derived.
