中文摘要：
瞬变电磁法对低阻体反应灵敏,是预报含水体较为有效的手段,所以利用瞬变电磁法对胶州湾海底隧道F1-2含水断层进行探测,排除信号采集和数据处理中的各种因素,通过对所处理结果的分析,判定了F1-2含水断层破碎带规模与位置,围岩风化程度、含水断层裂隙水发育情况,为超前预注浆加固提供了有效的地质信息。结合超前探孔、开挖后进行的地质编录,验证了本次瞬变电磁地质预报的准确性与有效性,对海底隧道含水断层的超前地质预报具有一定的借鉴和指导作用。
英文摘要：
Transient electromagnetic method is an effective way to predict the water for its sensitivity to the low resistance body,so it was used to detect the F1-2 water-bearing fault of the Kiaochow Bay subsea tunnel.The results were analyzed after excluding interfering factors in the signal acquisition and data processing.Finally the scale and location of the F1-2 water-bearing fault、and degree of rock weathering、growth of water-bearing fault fissure water were determined,these parameters provide effective geological information for the advance pre-grouting reinforcement.The advance exploration hole and geological record of this section proved the accuracy and effectiveness of this prediction,which will also be a very good reference and guide for succeeding tunnel geological predictios.
