| 摘 要： | 针对深圳地铁大剧院站至科学馆站区间小间距隧道工程,以地表沉降作为主要控制目标,对不同的施工方案进行了优化分析,也进一步对开挖路径和不同台阶长度的施工效应进行了优化分析,在此基础上,对该工程进行了施工过程的动态仿真分析。掌握了施工过程中地下结构和围岩的响应状态,分析结果表明:既有的施工方法是合理可行的,施工期间地下结构和周围环境没有安全隐患。这为工程的顺利实施提供了依据和指导,可供类似工程参考。 |

| Abstract: | Aimed at Shenzhen metro tunnelling with small interval,different construction projects are optimized based on land subsidence,and also excavation effects induced by different construction sequences and excavation path are analyzed.Construction processing of real engineering is simulated by 3-D elasto-plastic FEM.It is indicated that existing construction methods are reasonable during construction.The important conclusion that underground configuration and ambience are safe is arrived.The basis and guidance are supplied for real engineering and some meaningful conclusions are gotten as the reference for similar engineering. |
| Keywords: | tunnel engineering construction effect numerical simulation tunnelling with small interval optimal analysis shallow tunnel by excavation urban metro |
