物探方法在高速公路岩溶勘察中的综合应用

以杭金衢高速公路D、E合同段岩溶勘察为例,介绍了高密度电阻率法、自然电位法、探地雷达等工作原理和方法,解决了困扰建设的难题。通过在该高速公路施工勘察中的成功应用,说明了多种物探方法的综合应用对于互相对比纠正、正确解释地质现象和查遗补漏是有益和必要的。探测结果表明综合物探方法在岩溶探测具有不可替代的优越性,而且具有方便、经济、快捷和成果直观的特点。

With examples of karst prospecting in the hang-jin-qu highway D E contract ,the paper introduce high_density resistivity method and nature electricity potential method etc, the methods solved the difficult problems which stranded the building item. Along with succeeding applying in the constructing reconnaissance of the highway ,what integrating application of the many methods are for contrast & correctness, right interpreting geological phenomena and supplying miss is availability and necessary。The results show that the Comprehensive geophysical exploration has incommensurable advantages and also has many characteristics of Convenience,economy,shortcut and intuition.
