摘要
结合富溪双连拱隧道的实际施工方案,使用有限差分程序FLAC3D系统地研究了软弱破碎围岩浅埋偏压段施工的隧道变形和围岩应力变化规律,分析了现场监控量测数据,验证了数值模拟的正确性。
The thesis combines with the actual construction proiects of Fuxi double-arch tunnel, uses large finite difference program FLAC^3D, systematically analyze and research the changing law of the tunnel distortion and surrounding rock stress in soft and cracked surrounding rock condition. The thesis analyzes data of the field and validates the correctness of numerical simulation.
