摘　　要：为解决高速铁路路基填料造成的路基病害问题,本文提出掏挖换填病害区段路基填料的解决方案。首先搭建高速铁路轨道及路基试验段;其次研发掏挖路基填料特种工程设备;最后进行高速铁路路基填料掏挖试验。试验结果表明:所研制的特种工程掏挖设备可以实现对病害区段路基填料掏挖换填的目的,从而解决由路基填料或其他原因造成的路基病害问题。In order to solve the problem of subgrade disease caused by high speed railway subgrade filler,a solution of digging-filling subgrade filler in the defect section was proposed in this paper.First,the high speed railway track and subgrade test section were built. Secondly,the digging equipment of subgrade filler for special engineering was developed.Finally,the digging test of high speed railway subgrade filler was carried out.The test results show that the digging equipment can realize the purpose of digging-filling subgrade filler in the defect section,and can solve the problem of subgrade defect caused by subgrade filler or other reasons.
