摘要
水资源短缺已成为制约国民经济和社会发展的重要因素。寻找地下水资源,解决居民生产生活用水成为当务之急。论文以此为背景,对水源地的探测技术进行展开探讨。通过野外物理探测收集的数据利用Sufer8.0绘制等直线图来处理解释水文地质情况,本次探查目的为地下水富水性探测,圈定富水区域,本次探测收集的数据为奥陶纪石灰岩地层电阻率,正常情况下,奥陶纪石灰岩的电阻率很高,当有断层赋存,断层带往往成为一个导含水通道,成为地下水的富集带,从而导致电阻率降低;同时,当奥陶纪石灰岩中发育有充水岩溶时,电阻率值也会降低。因此,通过surfer8.0绘制电阻率等值线图及地层深度断面图来圈定低电阻率异常区域,将绘制的等值线图有效叠加,从而推断地下水富集的区域,利用此方法不仅经济有效,而且操作安全便捷,能为水文地质工作者寻找地下水资源提供科学依据。
Water shortage has become an important factor restricting the development of national economy and society.It is urgent to search for groundwater resources and solve the problems of water for production and living of residents.Based on this,discussions were made on the detection technology of water source.In this paper,field data was collected from physical detection using Sufer8.0 map such as straight line to handle and explain hydrogeological situation.The purpose of the probe here is to make detection in the underground water,delineating the rich water area,and the data collected here in the detection is Ordovician limestone formation resistivity.Under normal circumstances,the resistivity of ordovician limestone is very high,when a fault occurs,fault zone often becomes a water-carrying channel and a groundwater enrichment zone,which leads to the reduction of resistivity.At the same time,when water-filled karst is developed in the Ordovician limestone,the resistivity value will also decrease.Therefore,by drawing surfer8.0 resistivity contour map Therefore,drawing surfer8.0 resistivity contour map and strata depth profile to identify areas of low resistivity anomaly area,will draw isoline map overlay effectively,thus concluded that the area of groundwater enrichment is not only economical and effective,but also convenient and safe in operation using this method,and can provide scientific basis for hydrogeological workers looking for groundwater resources.
