| 摘 要： | 为了给公路设计部门提供选线依据,运用瞬变电磁法在山西境内的某两条高速公路隧道工程设计线路段上进行探测,以查明下覆不良地质构造的发育情况.通过对瞬变电磁法的探测能力进行理论上的讨论,对不同地电断面情况下的异常体电磁响应的定性分析,得出用瞬变电磁法探测不良地质体的可行性结论.经过资料处理,查出不良地质构造赋存的位置,解释结果与钻探资料完全吻合.

| Abstract: | In order to provide selecting basis to high way designing department, the transient electromagnetic (TEM) surveys ,with which the harmful geology structure of high way subsurface being detected,were carried out on two highway tunnels in Shanxi province. The detecting capability of TEM was discussed in theory , and the judge basis to electromagnetic abnormal response of different case of geoelectric bodies were analyzed. At last ,the feasibility that TEM can detect the harmful geological structures of highway tunnel engineering was reached. After data processing,the position of the harmful geological structure was located.The interpretation result coincides with the drilling one completely. |
