装配结构桥梁铺装厚度计算问题研究

Thickness Calculation of Deck Pavement of Built-up Bridge

装配式桥梁建造时会出现桥面铺装厚度过薄或过厚的现象,原因很复杂,但设计是一个重要原因.装配式桥梁的常规设计方法一般只能保证支座附近的桥面铺装厚度,桥梁的中间部分则无法保证.现有的桥梁计算程序大多都不考虑铺装厚度问题.笔者自编了铺装厚度计算程序,较好地解决了设计时理论铺装厚度的计算问题.

Deck pavement of built-up bridge may be too thick or thin due to complex reasons, among which a most important one is the design. Conventional method of designing built-up bridge can only ensure the deck pavement thickness near the ends of beams, without enough regarding of the middle part. Most of the available bridge calculation programs take no account of this problem. A new program is therefore developed to calculate the deck pavement thickness, which solve the problem successfully.
