| 摘 要： | 缺水基岩山区的找水定井难度较大,单一地球物理方法很难达到准确找水的目的。为了弥补高密度电法探测深度浅,受地形影响较大等问题,采用高密度电法联合瞬变电磁法对基岩山区地下水进行探测,高效经济地实现山区地下水资源精准勘查。在探讨高密度电法和瞬变电磁法的基本原理和联合探测可行性的基础上,介绍了联合探测的找水前提和依据,结合河北承德地区基岩山区地下水勘查的工程应用,讨论了地形对高密度电法的影响,分析了两种方法的联合探测结果,综合两者低阻异常对应区域最终确定了基岩裂隙含水区,并通过钻孔验证了综合地球物理技术在基岩山区找水的有效性,为今后在类似地质条件地区基岩裂隙水的勘查提供了理论和实践依据。

| Abstract: | The single geophysical method has great limitations in the exploration of water resources, especially in the areas with water-deficient bedrock mountain. In order to solve the problem of high-density electrical method, such as the shallow depth and the great influence of topography, the high-density electrical method combined with transient electromagnetic method(TEM)was used to explore groundwater in bedrock mountain area, aiming to realize accurate exploration of groundwater resources in mountain area efficiently and economically. Based on discussing the principle of high-density electrical method and transient electromagnetic method, and the feasibility of joint detection, the premise and basis of joint exploration of water resources were introduced. Meanwhile, combined with the engineering example of groundwater exploration in bedrock mountain area in Chengde area of Hebei, the influence of topography on high-density electrical method was discussed, and the joint detection results of the two methods were analyzed. The bedrock fissure water-bearing area was finally determined by combining the corresponding areas of two low resistivity anomalies, and the effectiveness of integrated geophysical techniques on the exploration of water resources in bedrock mountain area was verified by drilling holes. It provides theoretical and practical basis for the exploration of bedrock fissure water in similar geological conditions in future. |
