摘要
本文介绍了两种利用物探技术进行地质超前预报的方法 ,即地震负视速度法 (测试面与被探测面互为垂直的观测系统 )及地震横排列法 (震源孔和接收孔分别位于掌子面两侧的侧壁上 ,有规律地横向排列 )的原理及测试方法 。
By utilizing the geophysical exploration technique, the paper introduces two methods to put forward the geological super leading forecast during tunnel construction, i.e. the seismic responses arranged on the vertical cross sections in tunnel and the seismic responses arranged laterally on the side walls of the tunnel. The principles and testing methods of these two methods are described in detail and illustrated with two practical examples in this paper.
