【摘要】：以天津軟土地基小間距平行隧道為背景,在對實際加固方案分析基礎(chǔ)上,采用有限元程序ABAQUS對小間距平行隧道掘進過程進行了動態(tài)模擬,分析不同加固方式和加固范圍對先行隧道的影響,提出不同加固方式的影響規(guī)律與合理的加固范圍,并分析盾構(gòu)頂推力、隧道間距和地基土彈性模量等因素對先行隧道的影響。
[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.
