| 摘 要： | 在成都地铁项目工程中,盾构穿越大面积砂卵石地层在我国尚属首例。利用有限元软件ANSYS建立三维数值模型,研究了盾构在不同埋深、等代层厚度、掘进压力等工况下的沉降规律,提出了相关参数控制性建议,可为类似地层盾构隧道的设计施工提供参考。 |

| Abstract: | Shield tunneling across a large-area of sandy cobble stratum in Chengdu Metro is the first case in China.The finite element software ANSYS is used to establish a three-dimensional numerical model,and the settlement laws in different conditions including the buried depths,the thicknesses of equivalent circle zone and the excavation pressures etc.are analyzed,in order to propose the related parameters for control,design and construction of similar tunneling projects. |
| Keywords: | metro sandy cobble stratum shield tunneling surface settlement numerical simulation |
