南京奥体中心大平台温度应力监测与分析

为了减小温度应力对结构的影响，预防和控制温度裂缝，对混凝土结构的温度应力进行现场监测。以南京奥体中心大平台后浇带为例，运用温度应力计算理论和数值分析的方法对其进行温度应力监测及理论分析。结果表明，合理设置后浇带能有效地减小温度应力，使大平台达到安全性的要求。

Monitoring and analysis of temperature stress on Nanjing Olympic sports centre platform

In order to reduce the effect of temperature stress on the structure, prevent an d control temperature crack, the concrete structure should be monitored on the s cene. Based on monitoring and analysis of temperature stress by the theory of te mperature stress and the method of numerical value analys is on the post-poured belt device of Nanjing Olympic sports centre, it shows that the post-poured be lt device rightly set up could control temperature crack, reduce the effect of t emperature stress on the structure and make the platform meet the safety require ment.
