摘要
简述了在隧道施工前和施工过程中,为了避免施工风险和预防施工过程中可能出现的地质灾害,运用瞬变电磁法勘察含水层、断层、岩溶层等十分必要。通过工程实例,对瞬变电磁法的勘察原理、现场操作和勘察效果作了详细介绍,叙述了内业资料整理、资料解释和地质成果分析的过程,讨论了应用瞬变电磁法在勘察不良地质体中应注意的有关事项。
In order to avoid the risk from the construction and to prevent the possible geological disaster from the construction, this paper discusses the importance of using the transient electromagnetic method to detect the aquifer, fault, karst etc, before and during the tunnel construction. Iri addition, it introduces the principle of the transient-electromagnetic meth- od, the site operation and its effect, and it also describes the data sorting, data interpreting and the process of the geological result.
