半解析法确定大型桥跨结构的影响场

INFLUENCE FIELD DETERMINATION OF LARGE BRIDGE STRUCTURES BY SEMI-ANALYTICAL METHOD

摘要: 本文引出了影响场的概念,给出了用半解析分析法确定大型桥跨结构影响场的原理与方法:并以某大型悬索桥为例,计算了桥跨结构某处的应力影响场,得出了一些很有意义的计算与分析结果。

Abstract: The concept of influence field is introduced in the paper. The principle and the method to determine the influence fields of large bridge structures are also presented. As an example, some stress influence fields of a large suspension bridge were computed, and satisfactory results were obtained.
