| 摘 要： | 以成都地铁1号线工程天府广场北侧暗挖试验段为例,采用颗粒流数值分析方法,根据现场量测数据,对砂卵石地层浅埋暗挖地铁隧道进行了施工工法研究.研究认为:在卵石土层中,采用台阶法施工引起的地表沉降量略大于CD法,应加强对支护结构变形的监测.考虑到CD法施工工序复杂,施工扰动比台阶法大,而且卵石地层在未扰动条件下的自稳性较好,...

| Abstract: | Based on the test section by mining method for shallow Tunnels of Chengdu Subway Line 1,discrete element method and field measurement data were employed to study construction method for mining for shallow tunnels with pebble soil layer.The result indicated in pebble soil layer,settlement of earth's surface by bench method was bigger than that by the CD method;monitoring of the deformation of support should be conducted frequently.Due to the complexity of CD method,larger construction disturbance and self-st... |
