摘　　要：针对某铁路路堑工点运营期间的挡墙开裂、侧沟变形等病害,采用了工程地质调查、勘探、室内试验等综合手段,查明了滑坡的空间形态,对病害产生的原因进行了分析,根据对比反演参数和室内试验参数确定了滑面抗剪指标,评价了工点的稳定性。按照四项病害整治原则,结合正在实施的刷方卸载应急处理措施,制定了:方案一边坡大刷方卸载+局部锚固桩+框架锚杆+仰斜排水孔;方案二边坡局部刷方卸载+抗滑桩+框架锚杆+仰斜排水孔。经过方案比选,确定采用方案一,现场实施后,整治效果良好。On Aiming at the cracking of retaining wall and deformation of side ditch of a cutting point during the operation of a railway,this paper uses comprehensive means such as engineering geological survey,exploration and laboratory test to find out the spatial form of the landslide.At the same time,an analysis was conducted on the causes of the disease,and the shear resistance index of the sliding surface was determined based on comparative inversion parameters and indoor test parameters,evaluating the stability of the working point.According to the four principles of disease treatment,combined with the emergency treatment measures for earthwork excavation unloading,two treatment schemes are formulated:first,large excavation unloading of slope earthwork+locally anchor pile+frame anchor bolt+upslope drainage hole;second,partial excavation unloading of slope earthwork+anti-slide pile+frame anchor bolt+upslope drainage hole.After scheme comparison and selection,it is determined to use the first scheme,after the site implementation,the remediation effect is good.
