摘要:

深埋隧道的岩爆机理和岩爆预报预测一直是工程地质和岩石力学的热点和难点问题,已成为困扰地下工程发展的瓶颈之一。以滇藏铁路穿越三江造山带玉龙雪山南段的玉峰寺深埋隧道方案为例,在野外工程地质调查的基础上,对影响隧道岩爆的相关因素进行了系统分析。根据岩石力学试验、地应力分析和数值模拟计算结果,采用多种判据对玉峰寺隧道岩爆危险性进行了分析预测和综合评价。研究结果对于地质构造复杂区深埋隧道规划设计和岩爆灾害防治具有一定指导意义。

Abstract:

The mechanism and prediction of tunnel rock burst have been two main research issues in engineering geology and rock mechanics for many years, and become the choke points for underground engineering development. Taking an example from Yufengsi deep-buried tunnel of Yunnan-Tibet Railway which passes through the south part of Yulong Mountain of Three-river Orogenic Belt, factors related to tunnel rock burst are systemically analyzed on the basis of field investigation. According to the results of rock mechanics test, field stress analysis and numerical simulation, multiple criterions have been adopted to predict and comprehensively assess the risk of tunnel rock burst, which has important instruction to the deep tunnel design and the prevention of disasters associated to tunnel rock burst.

Key words: Three-river Orogenic Belt, deep-buried tunnel, rock burst, comprehensive assessment, Yunnan-Tibet Railway
