路堤状态的检测手段我国铁路鉴于近年来路堤变形和失稳现象日趋严重，在状态检测手段上加强了研制工作，力求改进沿用的地质勘探、钻孔取样、试验分析的传统作法，较快地得出稳定性评价．最早是将１２线地震仪用于工务部门，利用弹性波在不同上层中的传播规律分析路堤的状... In the light of the increasingly serious deformation and instability of embankments in recent years, the railway of our country has been strengthened in research and development of state detection methods to improve the traditional methods of geological exploration, drilling sampling and experimental analysis, Outstanding stability evaluation. The earliest is the use of 12-line seismograph for the public works department, the use of elastic wave propagation in different upper layer analysis of embankment shape ...
