钢箱梁桥SMA沥青路面温度场的数值模型

Numerical Model of Temperature Field in SMA Asphalt Road Surface of Steel Box Girder Bridge

在设计、铺装SMA沥青路面时 ,必须考虑对路面工作寿命有重要影响的温度因素。在物理简化的基础上 ,建立了钢箱梁桥SMA沥青路面温度场分析的数值模型。数值计算的结果与福建厦门海沧大桥及重庆鹅公岩大桥的实际测量数据具有较好的一致性。应用该模型 。

When paving SMA asphalt road surface, the temperature factor must be thought over which infects life-span of road surface. Winter and summer temperature distribution on a steel box girder bridge is simulated, compared with data measured on EGongYan Bridge in Chongqing and HaiCang Bridge in Xiamen. A change range of high road surface design temperature suit to China is given.
