依托武汉地铁11号线光谷四路站到光谷五路站施工段，研究盾构施工参数的选取对盾构管 片力学行为的影响，并针对可能出现的问题提出相应的控制措施。采用Abaqus 有限元计算软件对该工程中的S形曲线典型段的施工过程进行精细化仿真模拟，结合施工过程中典型监测点的长期监测资料，总结施工参数对隧道整环管片变形的影响规律，为施工过程中的隧道整环管片变形 预测与控制提供理论支撑。结果表明，围岩地质条件、注浆质量、土仓压力对盾构管片力学行为的影响较大，盾尾间隙对盾构管片力学行为的影响较小。将监测值与模拟值对比分析，发现两者 规律基本一致，说明对隧道工程进行数值模拟预测和仿真分析具有合理性和适用性。

Based on the construction section from Guanggu Fourth Road to Guanggu Fifth Road of Wuhan Metro No.11 Line, the impact of shield construction parameters on the mechanical behavior of shield segments was analyzed, and corresponding control measures were put forward. The FE code Simulia Abaqus was used to simulate the construction process of a typical S-typed section. The influence law of construction parameters on the segment deformation was summarized according to the long-term monitoring data of typical points, which served as the theoretical foundation for the prediction and control of tunnel′s domain segment deformation in construction stage. The results show that geological conditions of surrounding rock, grouting quality and the pressure of excavation face have greater effect on the me⁃ chanical behavior of shield segments, but the void of tail gap has less effect. Comparing monitoring data with simulation results, it is found that the law of the both are similar, which proves the method of numerical simulation on tunnel engineering is reasonable and applicative.
