    针对连续梁桥的混凝土桥面铺装层，建立了三维有限元计算模型，对温度荷载作用下桥面铺装层进行了应力计算和分析。分析结果表明，在温度荷载作用下，随着降温幅度的增加，混凝土铺装层内各应力最大值均呈单调上升趋势，各应力最大值增幅均较大。相关结论可为混凝土桥面铺装的设计和施工提供参考。

    The stress calculation and analysis on bridge pavement under temperature action were made by means of the three-dimensional finite element models of concrete bridge pavement of continuous girder bridge. The results indicate that all maximum stresses of concrete pavement increase monotonically with the decrease of temperature. And the amplifications of all maximum stresses are significant. The conclusion can be used for the design and construction of concrete bridge pavement.
