| 摘 要： | 张承高速公路施工过程中产生大体积滑坡,在滑坡的七个位置分别进行探坑取样,通过试验确定岩土特性和物理力学指标。现场调查表明,滑坡仍然产生蠕动变形。通过稳定性计算得到安全系数小于0.5,进一步开挖后安全系数只有0.36,由此提出科学合理的治理措施。

| Abstract: | There exists large-volume landslide during the construction of Zhangjiakou-Chengde Expressway.Through testing pits and sampling in seven locations of landslide,the rock-soil characteristics as well as physical and mechanical indexes are determined based on test.The field survey indicates that the landslide still has creep deformation.The safety factor is less than 0.5 via stability calculation,and it only achieves 0.36 after further exc-avation.On this basis,the scientific and reasonable management measures... |
