摘　　要： 对于超大跨度斜拉桥,在设计过程中必须考虑非线性因素对结构的影响。本文研究了千米级斜拉桥在施工阶段和营运状态的非线性效应,分析研究了非线性对斜拉桥受力与变形的影响,明确了非线性影响斜拉桥受力与变形的机理,并提出了减小超大跨度斜拉桥非线性影响的措施。 The influence of nonlinearities on very long span cable-stayed bridge structure must be considered in the design. In this paper, the nonlinearity effect of a cable-stayed bridge with span length over 1 1300 m at both construction and operation stages is studied. The influence of nonlinearities on the internal forces and deformation of the bridge is analyzed. As a result, the mechanism of the influence on the internal forces and deformation of the very long span cable- stayed bridge is made clear, and measures for reducing the influence on the bridge are proposed.
