摘要：
Based on the basis of observation data of box-beam temperature field, this study presented an comparative analysis of regulations on box-beam temperature gradient between China and foreign bridge engineering design, and proposed a new temperature difference distribution mode of concrete box beam along height of section. Finally, this study analyzed the external constraint temperature stress and temperature self-restrained stress of extra-long Longtan River bridge under different working conditions using ANSYS software, and compared them with measured results. This study provides reference for ...
