摘要
使用重迭回线瞬变电磁法对某拟建高速公路桥址进行了地下灰岩溶洞勘察,工作中采取了有效的观测装置形式,结合二维地电模型正演计算结果,对资料做出解释,查明了地下溶洞的赋存状态,探测成果得到了钻孔资料的很好验证。
In order to explore whether there are cavities or not underground,highway bridge site is detected by using overlap loop transient electromagnetic method.During working,suitable configuration is used.In combination with two-dimension geo-electric model forward calculation results,field data is processed and interpreted.Underground cavities are found out according to the interpreted result.The exploration conclusion has been proved by drilling data.
