工程物探在岩溶地区地质勘察中的应用——以费县电厂为例

Application of Engineering Geophysical Exploration in Geological Survey in Karst Area——Setting Feixian Power Plant as an Example

摘要:

结合费县电厂工程地质条件，运用高密度电阻率法和探地雷达勘察法，进行岩溶地区工程勘察，对2种方法的勘察结果进行比较分析，在此基础上进一步钻探验证。证实工程物探能迅速查明岩溶区的工程地质条件，勘察过程高效快速，达到地质勘察效果。最后针对岩溶区的拟建场地进行地基评价并提出地基处理方案。

Abstract:

Combining with engineering geological conditions of Feixian power plant, by using highdensity resistivity method and ground penetrating radar survey method, engineering survey has been carried out in karst area. Exploration results gained by using these two methods have been analyzed and compared, and further drilling has been carried out as well. It is proved that the engineering geophsical exploration can quickly identify the engineering geological conditions in karst area. The investigation process is fast and efficient, and it can achieve the good effect in geological survey. Pointing to proposed projects, foundation evaluation has been carried out and treatment program has been put forward.
