中文摘要:
      针对岩鹰鞍隧道穿越F4断层破碎带涌水涌砂快速泄水安全难题,运用数值模拟和最优化方法等手段,结合实际工程情况,建立了以排水支洞、迂回导洞和隧道正洞相对位置变化为研究对象的计算模型,并对4种不同工况进行了计算和分析。结果表明:排水支洞与正洞间距越小,正洞围岩的稳定性越差,应适当加大排水支洞与正洞之间的间距;结合排水机械的使用条件最终确定排水支洞、迂回导洞和隧道正洞的位置分布。
英文摘要:
      Aiming at solving the safety problems in rapid discharge of water and the sediment through Fault Fractured Zone F4 in the process of the construction of Yanying'an Tunnel, established in the present paper is a calculation model for the change in the relative positions of branch draining tunnels, the detour guide tunnel and the main tunnel by means of numerical simulation and optimization methods, with the four different working conditions calculated and analyzed. The result of our research shows that the smaller the distance between the branch draining tunnel and the main tunnel, the worse the stability of the surrounding rock of the main tunnel; therefore, the distance between the branch draining tunnel and the main tunnel should be appropriately enlarged, and the location distribution of the branch draining tunnel, the circuitous guide tunnel and the main tunnel should be finally determined according to the working conditions of the draining machinery.
