摘要:
以南京地铁3号线下穿秦淮新河段为例,采用正交优化算法与ABAQUS有限元计算相结合的方法,以盾构期及铺轨、运行初期的监测数据反演注浆圈等代层参数、铺轨荷载及等效行车荷载,根据反演参数预测隧道和堤防的长期沉降以及因上方河道修整引起的地铁隧道沉降,分析了隧道建设对河道渗流稳定性的影响。结果表明:反演得到的物理力学参数合理可信; 隧道及堤防沉降在地铁运营1000d时趋于稳定,河道开挖对地铁运行无影响; 修建地铁后河道的渗流稳定性能满足要求。
Abstract:
Taking Nanjing NO.3 subway passing under the new Qinhuai River as an example, combining orthogonal optimization algorithm with ABAQUS FEM, the equipollent layer parameters, track laying load and equivalent running load were inverted by monitoring data. The long-term settlement of the tunnels and the embankment, and settlement of tunnel caused by channel improvement were predicted based on the inversion parameters. The effect of tunnel construction on the channel seepage stabilization was also analyzed. The results showed that the physical and mechanical parameters obtained by the inversion were reasonable and credible; the tunnel and embankment settlement tend to be stable when the subway was operated for 1000 days, and the river excavation had no effect on the subway operation; the seepage stability of the river channel after the construction of the subway could meet the requirements.
