| 中文摘要: |
| 采用平面杆系有限元模型，根据天津站交通枢纽具体的盖挖逆作施工步骤,运用增量法模拟了整个结构的施工过程及后期正常使用阶段的结构受力状态，重点分析了从施工到使用阶段地下连续墙的受力状态。结果表明，该工程采用盖挖逆作法施工结构受力满足相关规范要求，可为类似工程的结构设计提供参考。 |
| 英文摘要: |
| Based on the detailed procedures of covered top-down construction method in Tianjin Station, using incremental method to simulate the mechanical behavior of station structures during the construction period and later service stage, the mechanical behavior of underground diaphragm wall was analyzed emphatically. The calculated results indicate that the stress of structure meets the requirement of related standards using covered top-down method in this project, which can provide a reference to the constructure design of similar project in the future. |
