| 摘 要： | 针对山区高水位隧道建立了研究隧道排水量及衬砌外水压力的简化模型,经过理论推导得出隧道排水量以及衬砌、注浆加固圈外水压力的解析公式,并将其应用于圆梁山隧道涌水量预测及排水量与衬砌水压关系研究.研究结果表明,随着隧道排水量的增加,衬砌水压减小,只有在考虑衬砌的排水性能即采取排水措施时才能发挥注浆加固圈对渗透水压的衰减作用,所得结论对于山区高水位隧道设计具有一定指导作用.

| Abstract: | In this paper, a simple model is established to study tunnel discharge and external water pressure on lining in high water level mountain area, and equations that can calculate tunnel discharge, external water pressure on lining and grouting reinforcement are deduced. Then these equations are used to forecast the discharge of Yuanliangshan tunnel and analyze the relation between water pressure on lining and tunnel discharge. The results show that water pressure on lining decreases with tunnel discharge growing, only when drainage measure is adopted can the grouting reinforcement play a role in reducing the seepage load. The conclusion is instructional for tunnel design in high water level mountain area. |
