Temperature Stress Analysis and Crack Control of Ultra-Long Structure in Metro Depot
In order to study the temperature stress and crack control of ultra-long structure under the action of temperature,based on the engineering design case of Wangfuzhuang Rolling Stock Depot of Jinan Rail Transit R2 Line,YJK software was used to analyze the temperature stress of cover plate.The results show that the influence of temperature on the cover plate connected to the fixed end is greater,and the influence of temperature on metro garage zone with higher stiffness is more significant.At the same time,the measures to control crack in engineer-ing are given,such as the use of prestressed technology and additional temperature reinforcement,practice has praved that this method has achieved good crack control effect.
