【摘要】 九寨沟县地区地下水资源丰富,自2008年汶川地震以来,受地震影响,多处存在山体滑坡和泥石流灾害,导致地表水源被滑坡体覆盖,地表水常年浑浊,难以满足山区日常用水需求。因此,在当地打井取水成了目前必要的工作。本次工作的任务是:配合传统地质勘查手段查明工作区内地下的含水层,储水层、储水点的分布、埋深、位置和地下水位情况,为布钻打井提供重要依据。结合工区地质情况、实际环境及工作任务综合分析,确定采用对称四极电测深法在工作区内进行勘探。通过对该区的勘探,基本查明了其地下水的含水层,储水层的分布、埋深等情况,为后续的布钻打井提供了重要的地球物理依据。更多还原

【Abstract】 The groundwater resource is abundant in Jiuzhaigou county area. Science Wenchuan earthquake in 2008,because of the influence of the earthquake,there are landslides and debris flow disasters in many places,surface water is covered by the landslides,surface water is turbid throughout the year. All of these cannot meet the requirements of the daily water in the mountain. So,it is necessary to dig wells for water there. The tasks of this work are finding out the distribution,buried depth,location and the underground water level of the underground aquifer,reservoir and water points in the workspace by the traditional geological prospecting means to provide important references of digging wells. Combined with the geological situation of the work area,the actual environment and the comprehensive analysis of the work tasks,the method of electrical symmetrical four-pole sounding is determined to prospect in the work area. The distribution and buried depth of the underground aquifer and reservoir are primitively found out by the exploration in this area. It provides important geophysics references to the subsequent digging.更多还原
