简支转连续桥梁施工力学及病害分析
|
摘要
简支梁桥转连续桥梁施工过程是结构体系的转变,在施工过程中往往会出现由于力和变形过大导致的结构损伤。本文从简支转连续梁的力学特征和施工方法的角度,分析了此类桥梁可能在施工期间存在的问题并加以关注,避免构件和结构体系的损伤。
The construction process of simple girder bridge to continuous bridge is the transformation of the structure system. In the construction process,structural damage caused by excessive force and deformation often occurs. In this paper,from the point of view of the mechanical characteristics and construction methods of simply supported continuous girder,the possible problems of this kind of bridge duringconstruction are analyzed and paid attention to,so as to avoid the damage of components and structural systems.
