长大深埋水工隧洞设计关键技术及实践研究

Research on Key Technology and Practice of Long and Deep Hydraulic Tunnel Design

为了进一步完善长大深埋水工隧洞设计方法,提出了涌水与高外水压技术、岩爆防治技术、软弱岩石大幅度形变预测及防治、高温处理技术研究。实践应用结果表明,提出的隧洞设计技术可以有效解决隧洞地质问题,在高地温和岩爆问题解决方面展现出较好的应用效果。

In order to further improve the design method of long and deep-buried hydraulic tunnels,this paper puts forward the research on water gushing and high external water pressure technology,rock burst prevention technology,large-scale deformation prediction and prevention of weak rocks,and high temperature treatment technology.The practical application results show that the tunnel design technology proposed can effectively solve the tunnel geological problems,and show good application effect in solving the problems of high ground temperature and rock burst.
