综合物探试验在火山岩溶地区高速公路路基探测中的应用

Integrated Geophysical Experiments in the Detection of Volcanic Karst Areas of Highway Subgrade

综合物探是采用不同的物探方法对目标体进行探测,以确定其所在地层情况、隐患位置及类型等详细信息,本试验通过对综合物探法在不同地质情况下探测信号的分析,建立各种地下目标体物探信号图像特征,总结出各种地质环境下的物探最佳组合方法、相应的仪器和工作参数等,最终提出适合本地区探测不良地质体的有效工程物探方法。

Integrated geophysical exploration work are made of different geophysical exploration methods to detect target body to determine goal body place stratum situation and hidden danger hidden types such as location,detailed information.This experiment through various geophysical exploration methods under different geological conditions detection signal analysis,to establish various underground target body of geophysical signal image features,summarizes various geological environment of geophysical exploration methods and corresponding optimal combination of instruments and working parameters,and finally puts forward for this area detection adverse geological exploration of effective engineering prospecting method.
