Abstract

Abstract: Deformation or local cracking appears in masonry arch bridge under the excessive external loadings to adjust its own constraints． The masonry arch bridge disease was studied based on Heyman analysis method，D.K.McNeely analysis method and Qian Lingxi analysis method.Three hinge failure mechanism and qualitative analysis mechanism of the pressure line were presented to determine the damage of masonry arch bridge．

Key words: bridge engineering, masonry arch bridges, failure mechanism, analysis method, plastic hinge

摘要： 圬工拱桥在外部过大荷载作用下将产生变形或局部开裂来释放自身约束。根据Heyman、D． K． McNeely 及钱令希机构分析方法，对拱桥病害进行分析，从理论上研究了圬工拱桥病害产生的机理，提出了三铰破坏机理和压力线定性分析机理，用以定性判断圬工拱桥病害产生的机理。
