Subgrade zoning, grading and layering disease treatment method after large deformation of high-speed railway foundation
The invention discloses a subarea, grading and layering disease treatment method for a roadbed after large deformation of a high-speed railway foundation. The subarea, grading and layering disease treatment method comprises the following steps: detecting compactness and shear wave velocity at the top of an embankment by using a high-density surface wave method and a geological radar method; according to the dynamic inspection vehicle data, identifying disease sections of the roadbed, and classifying the disease sections; the roadbed is divided into a passive area and an active area; for a district which is free of diseases and good in geology, the district is not treated; for a district without diseases and with bad geology, a passive area of the district is processed; for a common disease section, a passive area and an active area of the section are processed; for the serious disease section, the passive area and the active area are both processed; and monitoring the disease section. The method has the advantages that subgrade diseases of different degrees are effectively treated through accurate zoning, grading and layering treatment, so that the smoothness and safety of the track are maintained.
本发明公开了一种高速铁路地基大变形后路基分区分级分层病害整治方法，包括：使用高密度面波法和地质雷达法在路堤顶部进行密实度和剪切波速检测；根据动检车数据，识别路基的病害地段，并对病害地段进行分类；对路基进行分区，分为被动区和主动区；对于无病害且地质良好地段，对该地段不处理；对于无病害且地质不良地段，对该地段的被动区进行处理；对于一般病害地段，对该地段的被动区和主动区均进行处理；对于严重病害地段，对被动区和主动区均进行处理；对病害地段进行监测。本发明的优点是：通过精确地分区分级分层处理，针对不同程度的路基病害进行有效整治，以维护轨道的平顺性和安全。
