| 摘 要： | 利用三维有限元方法,计算研究大型断层区超前注浆加固后在TBM开挖过程中隧洞变形稳定情况.通过一系列算例计算,分别考察了隧洞埋深、注浆加固环力学特性和厚度、断层材料的力学特性等对隧洞变形稳定的影响情况,从而加深了对大断层区注浆加固规律性的认识,得出的结论可用于指导大断层区隧洞TBM施工超前注浆加固工作以及今后的研究工作.

| Abstract: | Three-dimensional FEM is used to calculate the deformation and stability of tunnel under tunnel boring machine (TBM) excavation in big fault zone after pre-grouting. A series of calculation is conducted to check influences of many factors such as overburden,mechanical properties and thickness of pre-grouting circularring as well as the mechanical properties of fault on the deformation and stability of tunnel so as to deepen the knowledge of pre\|grouting reinforcement. The conclusions from calculation can provide references for TBM excavation in big fault zone after pre-grouting and for future research. |
