| 摘 要： | 以深圳北站交通枢纽西广场工程为例，对超长混凝土楼板施工阶段进行长期的温度应力监测。运用有限元分析方法对该结构在施工阶段的温度应力进行模拟计算，并与实测结果进行比较分析。在实测和计算分析结果的基础上，得出超长混凝土楼板施工阶段的温度应力分布规律，即板中央应力较大，板边缘应力较小，并提出了有关设计和施工建议。 |
| 关 键 词： | 超长混凝土楼板 温度应力 有限元分析 监测 |

| Abstract: | Traffic Hub West Square of Shenzhen North Railway Station is taken as an example to carry out long-term temperature-stress monitoring during construction of super-long concrete floor. Finite element analysis method is used to carry out analog calculation of temperature stress during construction of such structure, and then the calculation result is compared with the actual test result. On basis of the test result and calculation result, distribution law of temperature stress of super-long concrete floor during construction is obtained, namely temperature stress decreases from floor center to floor edges, and related design and construction suggestions are given. |
| Keywords: | super-long concrete floor temperature stress finite element analysis monitor |
