    摘要:

    为解决在盾构法预制拼装隧道内做超前探水预报的技术难题,系统开展地球物理场理论研究,论证各种方法的优劣,并针对盾构隧道管片衬砌结构开展实验,改进超前探水预报探测方法,为超前预报人员提供参考。实验结果表明:通过对CFC法的观测方式进行改进,避开了隧道内金属机具等产生的电磁干扰,对盾构机刀盘前方围岩含水情况进行综合预报。

    Abstract:

    In order to solve the technical difficulties of making the advanced water exploration predictions in prefabricated shield tunnels, the theoretical research of geophysical field is systematically carried out to demonstrate the advantages and disadvantages of various methods. And the experiments are carried out for the segmental lining structure of shield tunnel to improve the advanced water exploration prediction method, which can be used as a reference for the other researchers. The experimental results show that through the improvement of the CFC observation method, the electromagnetic interference caused by the metal machines and tools in the tunnel can be avoided. The water content of the surrounding rock in front of the cutter head of the shield machine is comprehensively predicted.
