车载探地雷达在新建铁路路基质量普查中的应用

简要介绍了车载探地雷达原理、系统及在新建铁路路基质量普查中的应用情况。车载探地雷达，可迅速了解全线路基基床的状况和道床厚度等有关信息，以及探测桥涵两端与一般路基工后沉降等基床病害。经实地挖探验证与现场实际情况较为吻合。车载探地雷达，能够快速、准确、真实地检测路基的质量状况。

Application of Vehicle-borne GPR in General Quality Survey of Subgrade of Railways Newly Constructed

This paper introduced the principle and system of vehicle-borne GPR and its application in general quality survey of subgrade of railways newly constructed. This GPR may know the condition of subgrade bed and the thickness of track bed fast, and detect both ends of bridge and culvert, the post-construction settlement of subgrade and other bed diseases. Through field excavation, the detected information has demonstrated to coincide with the actual situation in the field. The practice has proved that vehicle-borne GPR can make a fast, correct and true inspection in relation to subgrade quality.
