南水北调西线工程深埋隧洞岩爆分析及预测
Study on Forecast of Tunnel Rock Burst in the West Route of South-to-North Water Transfer Project
摘要
Abstract
Rock burst is a typical geological disaster, how to forecast rockburst has become a hot and difficult issue in the research field of underground engineering.In order to evaluate the possibility of rockburst, based on the deep buried tunnel in West Route of South-to-North Water Transfer Project, combined with stratum litho logy analysis, in-situ stress measurement and the stress field inversion analysis, the stress field of tunnel after excavation was studied with finite element numerical simulation, tunnel initial in-situ stress field distribution along the axis also was researched, then the stress distribution of the tunnel surrounding rock after excavation was analyzed.In the end, the tunnel rockburst grade at different depths was analyzed and predicted.The results show that, the level of rockburst can be predicted accurately with this method, which will provide technical support for tunnel excavation supporting scheme and construction measures.关键词
