地面桥梁拓宽薄型梁设计

Design of Thin Beam in Widening of Ground Bridge

摘要:

以上海市某快速化工程为背景，分析了在受到边界约束条件限制的情况下，对既有桥梁进行拓宽的方法。分析表明：采用薄型梁结构，能够满足桥梁力学及功能的需求，是一种解决复杂拼宽桥梁的有效方法。

Abstract:

Based on a rapid project in Shanghai, under the boundary constraint condition, the thin beam structure is used to widen the existing bridges in order to meet the needs of bridge mechanics and function, which provides an efficient solution for complexly widening bridges.

Key words:widening bridge, thin beam, scheme design
