摘要: 为解决高原软岩隧道穿越富水地层关键难题,利用超前地质预报(TSP)等方法开展水害动态控制关键技术研究。首先,提出地下水高精度综合定量识别方法;然后,提出涌水量估算技术和涌水量动态监测的反坡排水及其优化技术,并结合敦格铁路长草沟隧道进行实例验证。研究结果表明:基于地震波、激发极化、地质雷达、瞬变电磁法的地下水高精度综合定量识别和涌水量估算技术,以及涌水量动态监测的反坡排水及其优化技术,可实现隧道施工期间的地下水动态风险管理;该技术可减少隧道施工风险,保证隧道施工安全,丰富隧道排水方法,同时,可保护隧址区的水源生态环境。

Abstract: In order to solve the key problem of the soft rock tunnel passing through the water-rich stratum on the plateau, the key technology of dynamic control of water disaster was studied by TSP. Firstly, the high-precision comprehensive quantitative identification of groundwater was put forward. Then, the estimation technology of water inflow and the anti-slope drainage and its optimization technology of dynamic monitoring of water inflow were put forward, which were verified by an example of Changcaogou tunnel of Dunge railway. The research results show that the technology of high precision comprehensive quantitative identification and estimation of groundwater inflow based on seismic wave, induced polarization, ground penetrating radar and transient electromagnetic method, as well as the reverse slope drainage and its optimization technology of water inflow dynamic monitoring, it can realize the dynamic risk management of groundwater during the construction of extra-long tunnel. This technology can reduce the risk of tunnel construction, ensure the safety of tunnel construction, enrich the methods of tunnel drainage, and protect the water source ecological environment of the tunnel site.

Key words: bad geology of plateau, soft rock tunnel, tunnel seismic prediction(TSP), water inflow, reverse slope drainage
