以武汉环球贸易中心(ICC)的深基坑项目为案例,通过分析现场实时监测数据,评估了基坑的变形状态及其对邻近地铁隧道的影响,采用MIDAS/GTS NX软件建立了数值模型,系统地进行了基坑开挖、支护过程及其对邻近地铁隧道的影响的数值模拟研究.研究结果显示,使用MIDAS/GTS NX软件进行的数值模拟分析与现场监测数据高度一致,并能准确反映基坑开挖过程中土体及周围建筑物的变形规律.因此,该研究为类似深基坑稳定性分析提供了宝贵实践经验,并解决了一系列实际工程难题.
Numerical simulation analysis of stability of deep foundation pit adjacent to subway tunnel
Taking the deep foundation pit project of Wuhan World Trade Center(ICC)as an example,the deformation state of the foundation pit and its influence on the adjacent subway tunnel were evalu-ated by analyzing the real-time monitoring data on site.A numerical model was established by u-sing MIDAS/GTS NX software,and the numerical simulation study on the excavation and support process of the foundation pit and its influence on the adjacent subway tunnel was systematically carried out.The results showed that the numerical simulation analysis using MIDAS/GTS NX soft-ware was highly consistent with the field monitoring data,and could accurately reflect the deformation law of soil and surrounding buildings during excavation.Therefore,this study provides valuable practical experience for similar deep foundation pit stability analysis and solves a series of practical problems.
