摘要
膨胀性软岩边坡稳定问题是吉珲高速公路建设中所面临的重要工程地质问题 ,为使路堑边坡加固方案合理 ,避免滑坡、塌方等现象的发生 ,基于吉珲高速公路膨胀性软岩试验研究结果 ,探讨了该地区软岩路堑边坡的变形力学机制 ,并以典型坡面为例进行了路堑边坡的稳定性分析 。
etc.Based on the situation of large-scale distribution of expansive softrock along Jilin-Hunchun speedway, taking advantage of the results of a series of tests including: uniaxial compression test, direct shear test, scanning electron microscope test etc., the paper presents the studies on the characteristics of expansive soft rock and performs stability analysis on cut slope, therefore, deformation mechanism is concluded, and remedial measures are proposed with reference to case history.
