Deformation characteristics of deep excavations for metro stations in Wuxi

  • 摘要: 收集了无锡市轨道交通一号线地铁车站深基坑工程的实测变形资料,统计分析了无锡地区以地下连续墙为围护结构的深基坑变形特性。结果表明,围护结构的最大侧移介于0.05%H和0.25%H之间,平均值约为0.12%H,最大侧移位置介于0.7H到1.1H之间,均值约0.9H;周边地表沉降介于0.05%H和0.13%H之间,平均值约为0.09%H;H为开挖深度。由于监测数据的离散性不利于分析不同因素对深基坑变形特性的影响规律,因此采用数值计算的方法进一步分析了开挖深度、围护结构插入比、首道支撑位置对深基坑变形的影响,得到若干规律性结果。
    Abstract: A database of many case histories of wall and ground movements due to deep excavations for metro stations in Wuxi Metro Line 1 is presented and discussed. The statistic analysis show that the maximum deflection of the retaining wall ranges from 0.05%H to 0.25%H, and the mean value is about 0.12%H. While the maximum deflection location ranges from 0.7H to 1.1H, and the mean value is about 0.9H. The ground settlement ranges from 0.05%H to 0.13%H, and the mean value is about 0.09%H. H is the excavation depth. Furthermore, factors affecting the wall deflection are investigated, and three of them, including excavation depth, embedded depth ratio and location of the first strut, are selected for numerical computation. Some conclusions are drawn from the artificial data.
