摘要
以朔黄铁路某高路堑护坡为研究对象,采用多种地质手段查明了坡体内部的地质情况,在此基础上,对该护坡病害特征及成因进行了分析,探索了重载铁路高路堑护坡病害的综合整治措施。利用传递系数法对该坡体进行了稳定性检算,最终确定以抗滑桩+锚索框架梁+平台封闭+堑顶封闭为主的综合加固方案,并布设临时观测点和永久观测点进行监测,结果表明:施工结束以来,护坡变形基本稳定,治理效果良好,可为类似工程的设计和研究提供参考。
Taking a high cutting protection slope of Shuohuang railway as the research object,the geological conditions inside the body of slope are found out by various geological means.On this basis,the characteristics and causes of the slope protection disease are analyzed,and the comprehensive treatment measures for the high cutting slope protection diseases of heavy haul railway are explored.The checking calculation on the stability of the body of slope is carried out by using the transfer coefficient method,and the comprehensive reinforcement scheme based on anti-slide pile+anchor cable frame beam+platform closure+cutting top closure is finally determined,and the temporary observation points and permanent observation points are arranged for monitoring.The results show that:since the end of construction,the deformation of the protection slope is basically stable and the treatment effect is good,which can provide reference for the design and research of similar projects.
