【摘要】 以金华江上某斜拉桥为研究对象,采用三维有限元方法对索梁锚固处集中应力效应进行了研究,分析中分别对三向预应力的施加方法、边界条件的取法进行了探讨,研究结果可供斜拉桥索梁锚固区的设计和施工参考。更多还原

【Abstract】 Taking a cable-stayed bridge over Jinhua River as the research object, this paper investigates the concentrated stress effect at the cable-to-girder anchor zone of the bridge by three-dimensional finite element method, and also respectively studies the methods for applying three-dimensional prestress and for selecting boundary conditions. The results of investigation herewith may serve as reference to the design and construction of cable-to-girder anchor zones of cable-stayed bridges.更多还原
