桥梁结构影响面加载及影响线加载

Loading on influence Surface & Influence Line of Bridge Structure

基于动态规划法加载原理,将桥梁结构传统的影响线加载拓展成影响面加载以便能获得桥梁结构(尤其针对宽度较大妁多格式箱梁桥、弯斜桥等)任一部分的最不利荷载效应值,并将两种加载方法进行了比较以供设计参考。

Based on the principle of loading by dynamic programming method, the traditional method of loading on influence line of bridge structure is developed to the new method of loading on influence surface, so the critical load effects of every part of bridge (especially for multiple box bridge, curved and inclined bridge with large width ) can be attained , and a comparison have been made between two loading methods to be referred to in design.
