摘要

直接测定地下水的流速流向一直是研究人员的目标之一,常用方法有电位差法、水文物探法、示踪法。本文在水位埋深较大的岩溶裂隙水井中,利用美国Geotech公司生产的地下水胶体探孔器,对监测井不同深度(239m、157m、101m)的地下水的流速和流向进行了测定,测试结果从下到上分别是:流向322.71°(北偏西37.29°),流速1496.56μm/s(129.3m/d);流向309.17°(北偏西50.83°),流速1032.0μm/s(89.16/d);流向26.76°(北偏东26.76°),流速754.06μm/s(65.15m/d)。测试的流向与由实际资料分析的地下水流向基本一致,速度从下到上逐渐减小。
        Directly measuring the velocity and direction of groundwater is always one of the objectives of the researchers. The common methods include the potential difference method, physical exploration method and tracer method. In this paper, the flow rate and flow direction of the monitoring wells at different depths(239 m, 157 m, 101 m) were measured by using the colloidal borescope produced by Geotech of USA. The test results are from bottom to top: direction 322.71°(37.29° North West), velocity 1496.56μm/s(129.3 m/d); direction 309.17°(50.83° North West), velocity 1032.0μm/s(89.16 m/d); direction 26.76°(26.76°North East), velocity 754.06μm/s(65.15 m/d). The test direction is basically the same as the flow direction of the groundwater, and the velocity gradually decreases from the bottom to the top.
