高密度电法在城市基础地质调查中的应用

Application of High Density Resistivity Method to Urban Geological Survey in Urumqi

城市基础地质调查工作的主要内容是查明城市发展区及规划区内的基础地质条件、隐伏地质构造及可利用地质资源。目前,高密度电法已在工程物探领域取得了成效显著的调查成果,本文将此方法推广应用在乌鲁木齐城市基础地质调查工作中,查明了工作区内隐伏活动断裂的位置及性质,有效识别出地层中的含水构造,圈定了煤矿采空区的埋深及空间展布形态,为后续城市地质调查工作提供有效的基础地质数据。

The main content of the urban basic geological survey is to find out the basic geological conditions in the urban development area and the planning area,the concealed geological structure and the available geological resources.At present,the high-density resistivity method has made remarkable achievements in the field of engineering geophysical prospecting.In this paper,this method is popularized and applied in the basic geological survey of Urumqi city.The location and character of hidden active faults in the working area are found out in detail and the water bearing structure in strata is identificated effectively.Also,the buried depth and spatial distribution form of the coal goaf are delineation. These provide effective basic geological data for subsequent urban geological survey.
