中文摘要: 国家新时期世纪工程川藏铁路面临着全球最为复杂的工程地质条件。受深部环境和工程扰动影响,沿线深埋隧道围岩失稳灾变问题凸显;符合深部特征的围岩灾变分析研究,既是川藏铁路深埋长隧安全建设的重大现实需求,也是提升特殊地质条件下深部工程开发能力的关键。为此,以深部围岩灾变分析为核心,从深部围岩孕灾的原位地质环境与工程扰动效应入手,重点开展深部围岩质量分级、大变形判识和岩爆孕灾等方面的理论方法研究与思考。首先,概述了川藏铁路深部围岩孕灾的原位地质环境特征,并从试验模拟和理论分析两个层次揭示了深部围岩孕灾的工程扰动效应;进一步地,以修正的BQ法为基础,发展了可综合反映地应力、地温和地下水影响的围岩质量分级方法,初步应用于川藏铁路深部多场耦合环境下的隧道围岩分级修正研究;最后,针对川藏铁路深埋隧道围岩灾变的两种典型显现形式(大变形与岩爆),提出隧道围岩大变形分级多因素分步评估方法,以及深部围岩岩爆综合预测研究思路和预测模型与方法。相关研究成果和学术思想可为川藏铁路沿线深埋隧道围岩灾变分析与稳定性研究提供借鉴与参考。
Abstract:The Sichuan-Tibet railway faces the most complicated engineering geological conditions in the world. Affected by deep environment and engineering disturbance, the instability and catastrophe of rock masses surrounding deep-buried tunnels along the line became prominent; the analysis and research on surrounding rock catastrophe that accord with the deep characteristics are not only a major practical need for the safe construction of deep-buried and long tunnels along the Sichuan-Tibet Railway, but also the key to improving the development capabilities of deep engineering under special geological conditions. Therefore, taking “the analysis of deep surrounding rock catastrophe” as the research core, starting with the in-situ geological environment and engineering disturbance effect of deep surrounding rock catastrophe, this paper focuses on the study and thought on theory and method of deep surrounding rock quality classification, large deformation identification and rockburst disaster. Firstly, the in-situ geological environment characteristics of deep surrounding rock disaster in Sichuan-Tibet railway were summarized, and the engineering disturbance effect on deep surrounding rock disaster gestation was revealed from two aspects of experimental simulation and theoretical analysis; furthermore, based on the revised BQ method, a classification method of surrounding rock quality which can comprehensively reflect the influence of in-situ stress, geothermal and groundwater was developed, which was preliminarily applied to the classification of tunnel surrounding rock quality under the deep multi-field coupling environment on Sichuan-Tibet railway; finally, aiming at the two typical forms of surrounding rock disaster (e.g., large deformation and rockburst) of deep-buried tunnels along Sichuan-Tibet railway, the multi-factor stepwise evaluation method of large deformation classification of surrounding rock, as well as the research idea and prediction model and comprehensive prediction method of deep rockburst were proposed. The relevant research results and academic ideas can provide a reference for the disaster analysis and stability research of surrounding rock of deep tunnels along Sichuan-Tibet railway.
