摘要
根据我国公路桥涵设计规范规定的温差分布和实际情况假定的温度场,利用ANSYS软件对简支空心板梁桥进行温差应力计算分析,计算结果表明温度应力在整个桥梁设计中占有很大的比重,且横向温差应力是腹板产生纵向裂缝的主要原因。
Based on the difference in temperature of "code for design of highway bridges and culverts" in China and the fact to presume temperature field, and the temperature stress of simple-supported box-beams is computed and analyzed, using ANSYS software. The analysis results show that the transverse temperature stress holds the very great proportion in the entire bridge design and the transverse temperature stress effect is the main reason causing the ventral plate to have longitudinal crack.
