摘要:
为分析浅埋隧道下穿密集管线施工地层与管线群变形时空特性，基于南昌地铁三号线邓埠站1号出入口暗挖隧道工程，利用理论分析、数值分析结合现场监测的方法进行研究。研究结果表明：隧道上方密集管线中位于前方的管线先承担开挖释放的部分土体应力，使其后方管线的变形大幅减小，平均减幅达23%；地层变形始终朝向掌子面，在掌子面到达时水平位移最大；因管线-土体共同作用，土体释放部分应力转移到地下管线，使地层沉降减小24%~38%，沉降槽宽度扩大40%；施工期间建议对污水管变形重点监测，在管线平均变形速率急速增大时，需提高监测频率。研究结果可为该地区相似工程施工提供参考。
Abstract:
In order to analyze the temporal and spatial characteristics of the deformation of stratum and pipeline group during the construction of shallow buried tunnel underpassing the dense pipelines,based on the underground excavation tunnel engineering at the No.1 entrance and exit of Dengbu Station in Nanchang Metro Line 3,the research was conducted by using the theoretical analysis,numerical analysis and field monitoring methods.The results showed that the pipelines located in front of the dense pipelines above the tunnel first bore part of the soil stress released by the excavation,so that the deformation of the pipelines behind them reduced greatly with an average reduction of 23%.The deformation of stratum always faced the tunnel face,and the maximum horizontal displacement occurred when the tunnel face arrived.Due to the pipe-soil interaction,part of the stress released by the soil was transferred to the underground pipelines,which reduced the stratum settlement by 24%~38% and increased the width of settlement trough by 40%.During construction,it was suggested to focus on monitoring the deformation of sewage pipes,and when the average deformation rate of pipelines increased rapidly,the monitoring frequency should be increased.The results can provide reference for similar engineering construction in this area.
