摘要
以贵州省余庆至凯里高速公路某边坡工程为依托,采用数值计算分析了该边坡的稳定性,计算结果表明该边坡处于不稳定状态,有必要对其进行加固治理。应用有限元程序从稳定系数、位移、剪应力等方面分析了挡土墙支护、抗滑桩支护、锚索框架梁支护及挡土墙-喷射混凝土-锚索框架梁联合支护4种支护方案的稳定性,并结合工程造价、环境条件、施工难易程度、工期等因素进行了综合分析。结果表明,该边坡的最优方案是挡土墙-喷射混凝土-锚索框架梁联合支护。
Based on a slope project of Yuqing Kaili Expressway in Guizhou Province,the stability of the slope is analyzed by numerical calculation.The calculation results show that the slope is in an unstable state,so it is necessary to strengthen and control it.By using the finite element program,the stability of four supporting schemes,namely,retaining wall support,anti-slide pile support,anchor cable frame beam support and retaining wall shotcrete anchor cable frame beam support,are analyzed from the aspects of stability coefficient,displacement,shear stress,etc.The results show that the optimal scheme of the slope is the combined support of retaining wall,shotcrete and anchor cable frame beam.
