【摘要】 介绍了一种新型的隧道施工超前地质预报系统USP,它利用地震波角度偏移技术,采用空间多分量、多波进行超前地质预报;它具有三维空间排布、多达256通道的数据采集;通过对三维数据结构的一系列处理分析形成三维空间地震波的各种图形图像,最终能探测灾害体的位置与形状参数,从而实现对隧道及地下工程前方地质情况的判译、预报。文中结合108国道南村隧道施工多次范围重叠预报说明该方法的预报效果,并进行开挖跟踪验证了方法的可靠性。更多还原

【Abstract】 This text introduces a new geological prediction system-USP(Underground Seismic Electromagnetic Prediction) for tunnel engineering.It uses seismic wave angle offset technology to process spatial multi-component and multi-wave for geological prediction.By using three-dimensional arrangement in space,256 channels of data collection,through a series of dispose and analysis of three-dimensional data structure,various graphs and images of seismic wave in three-dimensional space have been gained.Finally,it can detect the position and shape of catastrophic geological body to realize judging and prediction of geological condition in tunnel or underground project.This thesis compared many overlapping geological prediction results in Nancun tunnel of No.108 national highway and follows digging inspection to show effectiveness and reliability of USP.更多还原
