综合物探方法在福建高速公路隧道勘察中的应用

Application of the Comprehensive Geophysical Exploration on the Tunnel Survey of a Freeway in Fujian Province

在高速公路勘察前期,物探勘察能为高速公路线路的设计及其它勘察工作的布置提供基础资料。根据不同的地质条件以及勘察要求选择合适的物探方法,能达到事半功倍的效果。通过具体实例说明几种物探方法在福建省境内高速公路隧道勘察中的应用效果、存在问题及解决方法等。

On the previous period of a freeway survey, the geophysical prospecting reconnaissance can offer the base data for route design of a freeway and other investigation arrangement. If a comportable geophysical method takes it＇s choice according to the different geologic conditions and survey requirement, it is able to get twice the result with half the effort. Based on the examples of a site investigation by some geophysical prospecting methods, the paper presents the applied effect, subsistent problems and solution in the freeway tunnel reconnaissance within Fujian Province.
