摘要
虹桥临空11-3地块地下连接通道工程主体为一段双钢板-混凝土组合结构矩形盾构隧道,同济大学与上海市市政工程设计总院共同进行了相关衬砌足尺试验研究,研究其结构特性与受力机制。基于本项目及衬砌足尺试验,本文对项目的双钢板-混凝土组合结构矩形衬砌进行精细化数值建模,通过衬砌足尺试验数据进行对比进行验证,并数值模拟了矩形盾构隧道不同纵缝螺栓预紧力下的矩形衬砌结构变形与应变,分析了螺栓预紧力对矩形衬砌结构应变、变形的影响,总结了螺栓预紧力对矩形衬砌结构影响规律,讨论了该项目的最佳螺栓预紧力值。
The underground passage of 11-3 parcel at Linkong Road,Hongqiao District is a shield tunnel with composite section and Tongji University and Shanghai Municipal Engineering Design Institute carried out a research project on its mechanical performance including full-scale experiment on lining.On the basis of the project and relative research,this paper established an elaborate numerical model of the lining and verified it by data gained in fullscale experiment.By analyzing the deformation and strain in different bolt pretightening force gained by numerical analysis,the regularity of influence of it was acquired.Then a recommended bolt pretightening force of this project was discussed.
