摘要
蓬莱市北沟镇迎口山火山及周围为一新生代玄武岩台地,近年来区域经济发展过程中,周边工业用水量急剧增加,当地居民日常饮水十分困难.高密度电法作为一种有效的地球物理勘探方法在地下水资源调查、活动断裂探测等方面应用广泛.本文依据玄武岩地下水以原生孔洞、节理缝和次生裂隙等组成的裂隙孔洞储水层地质特点,选择高密度电法温纳α装置,在北沟镇迎口火山南侧2 km玄武岩地区寻找地下潜在水资源,通过6条高密度电法测量剖面(P1-P6),发现在P1和P2剖面中存在多段连续性较好的低阻异常区.低阻异常区均分布于一厚度大于30 m玄武岩高阻异常区之下,连续低阻异常在剖面垂直地面向下延伸范围较大,作为良好的地下水资源分布区得到了现有水井的验证.研究表明高密度电法在玄武岩区调查水资源是一种行之有效的技术方法,可为未来玄武岩区找水提供技术支撑.
Beigou town Penglai city Yingkou mountain volcano and the surrounding is a Cenozoic basalt platform.In recent years,with the regional economic process the surrounding industrial water consumption increased dramatically, the local residents of daily drinking water is very difficult. As an effective geophysical prospecting method, high density electrical method is widely used in groundwater resource investigation and active fault detection. In this paper, based on the original groundwater in basalt cavities, joint fissures and secondary cracks are composed of fissures and holes aquifers geological characteristics, the high-density electrical method is selected to find potential underground water in the 2 km basalt area in the south of volcano(P1-P6). It is found that there are many low-resistance anomalies with good continuity in the P1 and P2 profiles, and low resistivity anomaly areas are distributed in a thickness greater than the high resistivity anomaly zone of 30 m basalt under the continuous low resistivity profile in vertical downward range is large. The distribution of the groundwater resources as a good groundwater resource area has been verified by the existing wells,and the study indicats that the high density electrical method is an effective technical method for the future basalt area to provide technical support for water.
