摘要
南京奥体中心大平台为不设缝超长大面积现浇预应力混凝土结构。对平台的后浇带温度应力进行监测,监测结果表明:合理地设置后浇带能有效地减少温度应力对结构影响。介绍了大平台混凝土施工时采用的温度应力监测方案和实测数据,并对测试数据进行了分析,得出了几点结论。
The grant platform of Nanjing Olympic Center is seamless extra-long and big surface prestressing force concrete structure. The temperature stress in the back pouring band of the platform concrete is monitored, The result shows that setting the back pouring band reasonably can reduce the effect on structure due to temperature stress, the monitoring scheme about temperature stress of the large platform concrete construction is introduced, the observation data is analyzed and several conclusions are drawn.
