摘要
锦屏二级水电站引水隧洞具有工程地质条件极其复杂、埋深大、洞线长、洞径大的特点,为世界上规模最大的水工隧洞洞室群工程。通过对1号引水隧洞施工期安全监测资料的初步分析,掌握了变形、应力及渗流渗压的变化发展规律,为1号引水隧洞的安全评价提供科学依据,为2-4号引水隧洞的安全施工提供可靠技术支持。
The diversion tunnels of Jinping Ⅱ hydropower station are characterized as complicated engi- neering geological conditions, thick overburden, long length and large size in diameter, which make the tunnel project the largest hydro-tunnel group in the world. In this paper, based on preliminary analysis on the safety monitoring data during construction of the diversion tunnel No. 1 , the characteristics of de- formation, stress and seepage pressure were understood to evaluate safety behavior of the diversion tun- nel No. 1, and provide reliable technical support for safe construction of the diversion tunnels No.2-4.
