| 新建地铁车站上穿既有地铁隧道结构上浮变形预测(51 卷) |
| 英文标题 |
| Prediction of lifting and deformation of existing metro tunnel induced by newly-built metro station located above it |
| 摘要 |
| 依托北京地铁4号线西单车站上穿既有1号线区间隧道工程，分析了地铁上穿工程中所面临的风险点，建立FLAC3D数值计算模型，对既有线的上浮变形规律进行了研究，并预测了既有线隧道结构的最大上浮变形值为2.9 mm。预测值与现场监控量测结果2.3 mm比较接近，且纵向变形曲线形态相 |
