摘　　要：依托哈尔滨地铁3号线富水砂层叠落区间盾构隧道工程,建立ABAQUS有限元模型,模拟隧道掘进过程,同时与监测数据进行对比验证,检验该有限元模型的可靠性。模拟超前注浆和台车支护等控制措施,分析不同加固措施的作用机理与加固效果,对每种加固措施进行进一步优化,确定最佳支护方案,将各项最优支护方法结合在一起形成联合加固工法,并建立相应的评价方法,量化评定加固效果,最终提出最优加固方案。Based on a shield tunnel project in the water⁃rich sand layer of Harbin Metro Line 3,the finite element model of ABAQUS software is established to simulate the tunnel excavation process.Meanwhile,the reliability of the finite element model is verified by comparing it with the monitoring data.The control measures,such as advanced grouting and trolley support,are simulated,and the mechanism and reinforcement effect of different reinforcement measures are analyzed.Each reinforcement measure is further optimized to determine the best support scheme.The optimal support methods are combined to form a joint reinforcement method,and the corresponding evaluation method is established to quantify the reinforcement effect.Finally,the optimal reinforcement scheme is proposed.
