摘　　要：以山区外露桥台扩大基础基岩受影响为例,对桥台基础基岩加固思路、计算方法及计算过程进行了探讨,简化了Bishop法计算剩余下滑力计算过程。根据计算结果提出对桥台基础外露基岩正面进行锚索加固,侧面边坡采用钢轨桩加固的处理方案。实践证明,经加固处理后的桥台及边坡运行良好。Taking the exposed bedrock as an example,the reinforcement method,calculation method and calculation process of abutment foundation rock are discussed in detail.The calculation process of residual sliding force is simplified by Bishop method.According to the calculation results,anchor cable reinforcement is applied to the exposed bedrock face of abutment foundation,and the treatment scheme of rail pile reinforcement is applied to the side slope.The practice has proved that the abutment and slope after the reinforcement works well.
