TSP超前地质预报技术在鹧鸪山隧道中的应用

在隧道及地下工程的修建过程中,断层、破碎带易发生涌突水和坍塌等地质灾害,因此超前地质预报技术在隧道施工过程中尤为重要。阐述了TSP预报系统在隧道超前地质预报的基本原理和方法,结合工程实例进行超前地质预报试验,并将预报结果和实际开挖揭露的地质条件进行比较,进一步验证了TSP超前地质预报技术在隧道地质预报的准确性。

During the construction of tunnel and underground engineering, fault and fracture zone prone easy to occur geo-logical disasters such as water inrush and collapse, so advance geological forecast technology is particularly important during tunnel construction. The basic principle and methods of TSP200 forecast system in tunnel advance geo-logical forecast were introduced in this paper, taking advance geological forecast experiment which basing on engineering practice, and comparing the prediction results to practical geological conditions revealed after excavation,further verify the TSP technology advance geological forecast have a accurate forecast in tunnel geological.
