摘要
近年来随着高等级公路、城市道路和立交枢纽的快速发展,斜弯桥结构得以广泛的应用。为此,基于工程实例,对单跨斜支承梁的理论基础、内力影响因素进行了分析,并针对各种受力分析建立了统一的表达式,旨在促进该结构的进一步推广应用。
In recent years, curved skew bridge structure is applied widely with the rapid development of highway, city road and interchange. Therefore, this paper analyzes the basic theory, internal force factors of the single span skew girder combining with an engineering example, and it establishes a unified expres- sion aiming at all kinds of force analysis so as to promote the application of this structure.
