节理岩体中隧道开挖后渗流场重分布影响因素研究
Research on Seepage Field Redistribution of Tunnel in Fractured Rock Mass
摘要
Abstract
Tunneling in water-affluent area is likely to break the balance of seepage and form new seepage field, which may result in water outburst. Considering fluid-solid coupled interaction, this paper studies the effect of different crustal stress, water level and joint normal stiffness on seepage of tunnel in fractured rock. Causes of seepage changes resulted from different impact factors are analyzed by analyzing alterations of the width of fissure and water pressure before and after excavation. The conclusions may provide references for further researches on rock stability and water irruption.关键词
