直流电测深在铁路桥结合部台后路基勘察中的应用

Application of Direct Current Sounding on Roadbed Reconnaissance in the Railway Bridge Junction

铁路桥大都建在山沟、河流等一些地形复杂的地方。尤其是建在河流上的铁路桥,桥台后基常年受水流的冲击,容易形成洞穴、松软土、液化等一些地质现象,给铁路桥造成很大的危害。通过直流电测深法可以探测出洞穴、松软土、液化等一些地质现象的具体位置、大小。结合工程实例,介绍了直流电测深法在铁路桥结合部台后路基勘察中的应用。

Railway bridges are built in the valley, river and other complex terrain. Especially the railway bridge built on the river, their abutment bases are impacted perennially by water, and some damages such as caves, soft soil and liquefaction formed easily, which can harm to railway bridge. Direct. current sounding method can detect the In this paper, in the railway specific location and size of such caves, soft soil, liquefaction and other geological phenomena.
