【摘要】：新建铜九铁路杨家珑隧道处于软质层,地质环境较为复杂,开挖难度大。本文以杨家珑隧道作为研究对象,通过初步方案比选,通过数值模拟分析对比选出的方案进行计算,对工程施工方案奠定了设计基础,并通过施工过程,对施工方案效果进行评价。主要研究包括以下几个方面：(1)首先介绍了复杂环境下隧道施工的方法,以杨家珑隧道工程为研究对象,结合杨家珑隧道工程自身的特点,考虑地质条件、水文条件、现场情况等多方面环境因素,再从安全、质量、进度和经济性研究,选择最优的施工方案。(2)对杨家珑隧道应用CRD法进行数值模拟分析,得出的结论对杨家珑隧道的施工具有的指导意义。(3)通过考虑杨家珑隧道的综合因素,制定并分析了杨家珑隧道的施工方案。并采用监控量测手段对施工过程进行反馈。
[Abstract]:The new copper-nine railway, Yang's long tunnel, is in soft layer. The geological environment is complicated and the excavation is difficult. In this paper, Yang's long tunnel is used as the research object, and through the comparison of the preliminary scheme, the selected scheme is calculated by the numerical simulation analysis, and the design basis is laid for the project construction scheme, and the effect of the construction scheme is evaluated through the construction process. The main research includes the following aspects: (1) It first introduces the method of tunnel construction in complex environment, taking the project of Yangjiong Tunnel as the research object, combining with the characteristics of Yang's long tunnel project, taking into account various environmental factors such as geological conditions, hydrological conditions and on-site conditions. The optimal construction scheme is selected from the research of safety, quality, progress and economy. (2) The numerical simulation of Yang's long tunnel is carried out by using the CRD method, and the conclusion is of great significance to the construction of the Young's long tunnel. (3) The construction scheme of Yang's long tunnel is developed and analyzed by taking into account the comprehensive factors of Yang's long tunnel. And the monitoring and measuring method is adopted to feed back the construction process.
