摘要
深埋隧洞高地应力岩爆、大变形灾害已经成为制约地下工程施工的重要影响因素,对地应力的研究了解深部岩体破坏机理及相应的防治对深埋隧洞的设计和施工具有实际意义.依托西安市引蓝济李引水工程高地应力测试成果结合施工期深部岩体的破坏形式进行分析研究,并提出相应的防治处理措施,可为类似工程的勘察设计施工提供经验与指导.
Abstract
The high stress rock burst and large deformation disas-ters caused by deep buried tunnels have become important influ-encing factors that restrict underground engineering construction.Therefore,conducting research on geostress,understanding the mechanism of deep rock mass failure,and corresponding preven-tion and control measures have practical significance for the de-sign and construction of deep buried tunnels.Based on the high ground stress test results of the Xi'an Blue to Li Water Diversion Project,combined with the analysis and research of the failure mode of deep rock mass during construction,corresponding pre-vention and control measures are proposed,which can provide ex-perience and guidance for the survey,design and construction of similar projects.
