钢-混凝土组合箱梁桥沥青摊铺温度场的试验与理论对比分析
Temperature experiment and analysis of steel-concrete composite girder bridge caused by asphalt paving
摘要
Abstract
During asphalt paving,the bridge structure was affected by hot asphalt,solar radiation,convection and radiative heat transfer between air and the surface. The boundary is complex and so the temperature field is variable with time and space. The feature was generalized after the test and measurement of actual bridge,south connection line of Runyang Bridge.By means of ANSYS software,the final calculation program was found out by analyzing tridimensional model,longitudinal and transverse plane model. A certain number of transverse planar models can be used to represent the temperature of whole bridge,which is verified by comparing the theoretical calculation and observed value.关键词
