摘要
水利水电洞室具有规模大、尺寸大的特点,如果开挖隧洞发育大型不良地质(断层破碎带、溶腔、突水突泥等),则更容易引发大型的安全生产事故,而水电隧洞超前地质预报工作相对薄弱,因此开展水电洞室超前地质工作是一种新的应用和研究。首先介绍了TSP技术的发展现状和基本原理,探讨了影响TSP数据采集的几点关键因素;之后,将TSP方法应用到乌东德水电站的泄洪洞和导流洞中,获得了大尺寸工作面水工洞室超前地质预报结果,并绘制出不良地质体3D空间分布成果。该结果与随后施工开挖揭露出的溶洞以及工作面前方存在的导流洞水体分布基本一致,验证了TSP技术在水电水利地下工程中应用的可行性和有效性,具有一定的应用推广意义。
Large-scale safety accidents are prone to be triggered by large geological defectives (broken fault zone, cave, and water gushing and mud) in large hydropower caverns. Advanced geological prediction for hydroelectric tunnel is relatively weak. In this research, the development status and basic principle of TSP (tunnel seismic prediction) technology are firstly introduced, and some key factors that affect TSP data acquisition are discussed. Furthermore ,TSP technology is applied to the geological prediction for the discharge tunnels and diversion tunnels of Wudongde Hydropower Station. The geological prediction result of large working face is obtained, and the 3D spatial distribution of the geological defectives is given. The forecast results are basically in accordance with the excavation results which exposed karst caves and water distribution in front of excavation face. The prediction results verify the feasibility and effectiveness of the application of TSP technology in underground engineering of water conservancy and hydropower projects.
