摘要:
论文依托新建兰渝高铁桃树坪富水弱胶结粉细砂隧道工程，基于现场监测和数值模拟分析相结合的方法，对大断面富水砂地层条件下的隧道施工方案进行了优化和分析，研究了大断面隧道CRD法、双侧壁导坑法和三台阶七步法三种施工方案的优缺点，改进了大断面隧道双侧壁导坑法施工技术，提出了“底部双导洞超前施工”的新工法。跟踪桃树坪隧道 3#斜井施工工区底部双导洞超前工法试验段进行的现场围岩压力、拱顶沉降和水平位移的现场监测，验证了工法的安全、可行性；基于数值模拟分析，确定了施工中上半断面的最佳开挖高度 5.4 m，超前导洞1部与上半断面5部间合理步距 25 m，优化了底部双导洞超前施工工法的技术参数，为富水弱胶结粉细砂地层隧道的施工提供了技术保障。
Abstract:
Taoshuping tunnel, the new constructed of Lanzhou-Chongqing railway, has a complicated geological condition of rich water and weak cemented fine sand. Combined with the method of in-situ monitoring and numerical simulation, the large cross-section tunnel construction scheme under the geological condition of rich-water and fine sand are analyzed and optimized. On the basis of compared the advantages and disadvantages by CRD method, double-side-drift method and three steps seven footwork excavation method, the double-side-drift method for large cross-section is improved and a new method of bottom advanced double-drift method is proposed. The security and feasibility of the new method are proved by in-situ monitoring the surrounding rock pressure, vault settlement and horizontal convergence of Taoshuping tunnel 3# inclined shaft’s test section. Based on the numerical simulation, the technical parameters for the new method is optimized. The simulation results show that the optimum excavation height of upper section is 5.4 m and the most reasonable step distance between the 1st part (advanced double-drift) and the 5 th part (upper section) is 25 m. The research results provided a technical support for tunnel construction under the condition of rich and weak cemented fine sand stratum.
