摘要
隧洞穿越地区地形复杂,隧洞工程勘察难度大,钻机施工困难,物探工作难度大,快速有效地开展工程勘察安全性评价工作对后期施工具有重要意义。以某项目为依托,综合利用以往地质资料,采用温纳和斯伦贝谢两种装置高密度电法工作,分析其不同装置高密度电法工作原理及应用效果。温纳装置探测深度较大,横向分辨率较高,高阻异常体特征反映较明显;斯伦贝谢装置探测深度相对较浅,其垂向分辨率较高,抗干扰能力强,低阻异常体反映较明显。
The tunnel passes through areas with complex terrain,and it is difficult for tunnel exploration and drilling,which causes difficulties for geophysical exploration.It is of great significance to carry out the safety evaluation of engineering exploration quickly and effectively for the later construction.Based on a project and comprehensive utilization of previous geological data,Wenner and Schlumberger devices were used for high-density electrical method.The working principle and application effect of high-density electrical method in different devices were analyzed.The Wenner device has large detection depth,high lateral resolution and obvious reflection of the characteristics of high resistance abnormal body.The Schlumberger device has relatively shallow detection depth,with high vertical resolution,strongly anti-interference ability and obviously reflection of low resistance anomaly body.
