地下工程施工超前地质预报系统研究

介绍一种新型的地下工程超前地质预报方法与系统。该系统采用“角度＋位置偏移的联合体系”进行空间多分量、多波超前地质预报。它利用三维的空间排布、多达256通道的数据采集、多震源点位置偏移，进而构成在隧道掌子面前方高密度的三维数据结构体。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，最终计算岩土体多种力学参数，从而实现对隧道及地下工程前方地质情况的判译、预报。并结合在隧道及地下工程的应用实例说明三维空间地震勘探在地下工程超前地质预报的广泛用途。

Research on Geological Prediction System of Underground Engineering Construction

This paper introduces a new geological prediction method and system of under- ground engineering construction. It uses ＂ the united system angle and position offset＂ to carry on the multi-component installation of space and multi--wave geological prediction. It makes use of three--dimensional space arrangements, 256 channels data collection and many shot position offset so as to compose three--dimensional statistic structure. By a series of processing and analyzing the three--dimensional space various graphs and images of seismic wave, many mechanical parameters of rock and soil are computed.
