摘要
对于我国中西部地区来说,越来越多的水利工程建设涉及深埋长输水隧洞。通过引江补汉工程可研阶段工程地质勘察,分析和研究了深埋长隧洞存在的涌水突泥、高外水压力、高地应力条件下软岩大变形、坚硬岩岩爆及其对地表水和地下水环境影响、围岩稳定、有害气体、高地温等主要工程地质问题,为隧洞工程设计、施工提供了可靠的技术支撑,为类似深埋长隧洞工程提供参考借鉴。
For the central and western regions of China,more and more projects select deep buried and long water conveyance tunnels.Through geological survey in feasibility study stage of the River Diversion Project from the Yangtze River to the Han River,geological problems existed in deep buried long tunnel,such as water inrush and mud inrush,high external water pressure,large deformation of soft rock under high ground stress,hard rock burst and its impact on surface water and groundwater environment,surrounding rock stability,harmful gas,high ground temperature and so on,have been analyzed and studied,which may provide technical support and reference for the design and construction of deep and long tunnel projects.
