【摘要】：以天津软土地基小间距平行隧道为背景,在对实际加固方案分析基础上,采用有限元程序ABAQUS对小间距平行隧道掘进过程进行了动态模拟,分析不同加固方式和加固范围对先行隧道的影响,提出不同加固方式的影响规律与合理的加固范围,并分析盾构顶推力、隧道间距和地基土弹性模量等因素对先行隧道的影响。
[Abstract]:Based on the analysis of the actual reinforcement scheme, the driving process of the small spacing parallel tunnel in Tianjin soft soil foundation is simulated by the finite element program ABAQUS. This paper analyzes the influence of different reinforcement methods and reinforcement range on the advance tunnel, puts forward the influence law and reasonable reinforcement range of different reinforcement methods, and analyzes the influence of shield top thrust, tunnel spacing and elastic modulus of foundation soil on the advance tunnel.
