为查明习水至古蔺高速公路赤水河大桥桥梁墩台区域岩溶的发育特征，采用大地电磁测深法（EH4）对施工前桥梁墩台区域纵断面进行勘探。在线路向左25m、深度为100m处，EH4法视电阻率为一圈闭的高阻区，判释为干溶洞，与现场钻孔地质资料对比，证实了EH4判释结论与实际地质情况完全吻合。

In order to find out the characteristics of karst developing in pier area of Chishui River Bridge which is a part of Xishui County to Gulin County highway, the EH4 electromagnetic sounding method was used to ex?plore the vertical section of the bridge pier placed on. At a distance of 50 meters and 100 meters deep on the left side of the highway, the apparent resistivity was measured by with the EH4 electromagnetic sounding method showing a trap of high resistance region and interpreting as an empty karst cave. The results of EH 4 electromag?netic sounding method measured was compared with the drilling geological data in the field showing the results of EH4 coinciding with the actual geological condition.
