摘要

深埋隧洞工程越来越多，但相关工程经验积累不足，设计和计算方法远未成熟，深埋隧洞工程设计和施工安全控制需要大量现场监测和测试数据的支撑，而现有的监测和测试设计方法均针对浅埋工程的特点提出，在深埋隧洞施工过程中应用时遭遇到极大挑战。为此，首先依据现场揭露现象和多种先进观测技术获得的成果，分析了深埋硬岩隧洞施工期围岩的开挖力学响应特征和运行期衬砌的力学响应特征，剖析了现今主流观测方法存在的问题，提出了6条关于深埋隧洞典型断面监测和测试设计的建议，为促进此类工程相关设计方法的完善提供参考。

Abstract

Nowadays the number of deep tunnels is greatly increased. Since there are lacking successful numerical methods and experiences from relevant engineering construction and design of deep tunnels

massive on-site monitoring and testing should be conducted to support the design and safety control. The present monitoring and testing design methods are proposed according to the characteristics of shallow underground engineering. However

when they are introduced into the deep tunnels

great challenges are encountered. In this study

the failure of surrounding rock mass in the field was presented and then the deformation and failure responses of surrounding rock mass were obtained during excavation by various advanced observation techniques. Based on the acquired information

this study analyzed the mechanical response characteristics of surrounding rock mass during excavation and lining at the operating period. Then we discussed the problems arising from the application of current modern monitoring methods. Six suggestions were put forward relating to the monitoring and testing design of the representative section in the deep tunnel. This study can provide helpful guidance to improve the design methods in similar projects.
