空心板桥桥面铺装三维有限元法分析

以较常用的8m、13m、16m、20m、30m跨径空心板桥为代表，通过分析铺装层破坏形式．将空心板梁体和水泥混凝土铺装层视为一个相互作用的统一整体，利用有限元软件进行空间实体建模和计算，从而对不同跨径空心板桥水泥混凝土铺装的荷载应力进行分析，并计算分析不同形式铰缝对铺装层的应力影响，最终可得出空心板桥水泥混凝土铺装的应力规律。

Three-dimensional Finite Element Analysis of Deck Overlay on Hollow Slab Bridge

With the common 8m, 13m, 16m, 20m, 30m span hollow slab bridge as representatives, the bridge deck and cement concrete overlay are considered as an interaction unified whole. Finite element software is used to establish solid model and do calculations so that the load force of cement concrete overlay of different span hollow slab bridge is analyzed and the analysis and calculations are conducted about the stress influence of different kinds of hinge joint. In the end the stress law is deduced concerning cement concrete overlay of hollow slab bridge.
