摘要
在城市中,存在着大量的多物理属性背景干扰,其中以地质发育,工业、民用电磁信号,城市噪声等为主要影响。视电阻率垂向电测深方法具有垂直方向分辨率高、装置简易、工作效率高的优点被广泛应用于城市地质环境勘查。本次在无锡市完成3条总长3160 m的测线E1、E2、E3,结合以往的勘查以及对异常区的钻探验证,结果显示在勘查区存在2条断层F1、F2,并且在垂向划分了岩层,确定了富水区域,取得了优良的应用效果,为无锡市地质环境评价提供了参考依据。
In the city,there are a lot of multi-physical background interference,including geological development,industrial,civil electromagnetic signals,urban noise and so on.The apparent resistivity vertical electric sounding method has the advantages of high vertical resolution,simple device and high working efficiency,and is widely used in urban geological environment exploration.This time,three lines of E1,E2 and E3 with a total length of 3160 m were completed in Wuxi city.Combined with previous surveys and drilling verification of anomalous areas,the results showed that there were two faults F1 and F2 in the exploration area,and the rock layers were vertically divided.The water-rich area was determined and the excellent application effect was obtained,which provided a reference for the geological environment evaluation of Wuxi city.
