摘要

隧道前方含水构造的超前预报是地下工程领域中亟待解决的难题。基于频域激发极化法中频散率参数对水体响应敏感的特点，将其引入到隧道含水体超前探测研究工作中。从理论正演、物理模拟、解译方法等方面入手对频域激发极化超前预报技术进行了系统的研究。利用三维有限元数值模拟技术解决了隧道中频域激发极化超前探测的数值正演难题，并通过对典型含水体的正演研究得到了视频散率对含水构造的响应规律，发现视频散率曲线的极大值是表征掌子面前方含水构造存在的重要特征；基于大量数值正演的结论，提出了一种利用两次探测的视频散率曲线极大值联合判断含水构造位置的方法；物理模型试验和现场实际应用表明，频域激发极化法预报的含水体位置与实际情况基本一致，验证了该方法用于隧道含水构造超前探测的有效性，为解决隧道含水构造超前探测这一难题提供了可行的途径。

Abstract

The detection of water-bearing structures is the key problem needed to be resolved. Apparent percent frequency effect as one parameter of frequency domain induced polarization (IP) is sensitive to water. And frequency domain IP is introduced to water-bearing structure advanced detection in tunnel. Frequency domain IP on advanced detection about theoretical forward

physical simulation and interpretative method is researched systematically. Firstly

the problem of numerical forward on advanced detection of frequency domain IP is solved by using finite element method. The response pattern of apparent percent frequency effect to typical water-bearing structures is found by forward modeling systematically. The maximum of apparent percent frequency effect curve has important characteristics

for which water-bearing structures exist ahead of tunnel face. Secondly

the method of joint judging the location of water-bearing structures using two maximum of apparent percent frequency effect curves is put forward

basing on large number conclusions of numerical forward. At last

the physical model test and engineering application show that water-bearing structure location of advanced detection of frequency domain IP is almost in agreement with actual situation. Frequency domain IP is efficient in detecting water-bearing structures. And it provides a feasible approach to solve the problem of advanced detection of water-bearing structures
