摘　　要：近年来,随着我国隧道及地下工程的飞速发展,突涌水等不良地质条件逐渐成为制约地下空间发展的重要因素,采用TGS360Pro超前地质预报技术(tunnel geology survey,简称TGS)提前探测掌子面前方的富水不良地质体,对于保证隧道及地下工程的安全开挖具有重要的意义。介绍了TGS360Pro超前地质预报技术的原理及数据采集方式;分析了TGS360Pro超前地质预报技术的数据处理及其对预报结果的影响;阐述了对滇中某隧道超前地质预报结果进行的数据处理与分析,准确地预报出该隧道掌子面前方拱顶的突水不良地质情况;证明了TGS360Pro超前地质预报技术对突涌水不良地质情况具有很强的识别能力,旨在为今后TGS360Pro超前地质预报方法在突涌水不良地质情况预报中的应用借鉴。In recent years,with the rapid development of tunnels and underground projects in China,adverse geological conditions such as sudden water inrush have gradually become an important factor restricting the development of underground space.The use of TGS360Pro Tunnel Geology Survey(TGS)to detect water-rich and geological anomalies in front of the tunnel palm face in advance is of great significance for ensuring the safe excavation of tunnels and underground projects.This paper introduces the principle and data acquisition method of TGS360Pro technology,analyzes the parameters that affect the processing of TGS360Pro data and their impact on the prediction results,selects the advanced geological prediction results of a tunnel in central Yunnan for data processing and analysis,accurately predicts the geological anomalies of water inrush from the arch in front of the tunnel palm face,and proves that TGS360Pro technology has strong recognition ability for geological anomalies in sudden water inrush,intends to provide reference for the application of TGS360Pro method in predicting adverse geological conditions caused by sudden water inrush in the future.
