| Abstract: | 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. |
