物探直流电法在隐伏岩溶地区找水中的应用

丰润东部城区地处燕山南麓的山前倾斜平原，区内地下水分布不均，局部缺水严重，区内地质条件较复杂，找水难度极大。在近年丰润地区隐伏岩溶区缺水区找水工作中，以地质成因控水理论为指导，综合物探勘查、钻探验证等技术手段，成功实施了地下水勘查示范案例，通过对实例的分析，指出要高度重视野外水文地质调查与物探直流电法相互验证，能有效的提高隐伏岩溶地区找水的经验。

The Application of Direct Current Method for Water Resource Search in the Covered Karst Region

Eastern region of Fengrun city is located at a piedmont clinoplain in the south of Yansan Mountain. As ground- water distribute unevenly, some parts of region have an acute shortage of water. Moreover, the complicated geological condition makes it hard to search water resource. While in recent years, based on geologic origin affecting water distribution theory, researchers have successfully finding water resource by using geophysical prospecting method. The paper analyzes real cases and concludes that combination of hydrogeological condition field survey and direct current method contributes to gain experi- ence in water resource search in covered karst region.
