摘要
为研究不同铺装层材料对箱梁温度场的影响,以槎滘大桥为工程背景,采用有限元软件分别对水泥混凝土铺装层与沥青混凝土铺装层在不同厚度下的温度场进行计算与分析,并比较了两种不同铺装层的温度场.分析结果表明,沥青铺装层更适合作预应力混凝土桥梁铺装层,且其厚度宜在5-15 cm之间.
In order to study the effect of the temperature distribution in different materials under the pavement layers of the box-girder, taking Chajia Bridge as a background, the finite element software is used to calculate the temperature distribution of the cement concrete pavement and asphalt concrete pavement with different thickness, and two different pavement temperature fields are compared. All the results show that asphalt pavement is more suitable for the prestressed concrete bridge pavement, and the appropriate thickness is from 5 cm to 15 cm.
