摘要
针对在建怀邵衡铁路岩鹰鞍隧道F4断层,为解决隧道施工过程中遇富水含砂断层安全风险,通过对隧道涌水涌砂风险数据分析、方案比选、力学验算确定合理的施工参数,研究形成完善的隧道内高位逃生方案。结合怀邵衡铁路岩鹰鞍隧道高位逃生方案在应急演练中成功应用,确定了涌水涌砂地质高位逃生方案的合理性。实践表明,在易发涌水、涌砂隧道施工中的高位逃生方案优势明显,可为矿山、公路、铁路以及其他类似隧道工程提供参考。
Aiming at the F4 fault of Yanying＇ an Tunnel in Huaihua-Hengyang Railway, in order to solve the security risk of water-rich sandy fault in the process of tunnel construction, this paper determined the reasonable construction parameters by analyzing the risk data of water and sand gushing in tunnel, comparing several schemes and checking the mechanical computations, and studied a perfect high-position escape scheme in tunnel. Combined with the successful application of high-position escape scheme in the emergency rehearsal of Yanying＇ an Tunnel, the rationality of high-position escape scheme for water and sand gushing geology was determined. Practice shows that the high-position escape scheme has obvious advantages in the construction of water and sand gushing tunnel, and it could provide a good reference for mine, highway, railway and other similar tunnel projects.
