摘要
以矮塔斜拉桥为工程背景,考虑矮塔斜拉桥在施工过程中的体系转换与非线性效应的影响,采用桥梁专用计算软件MIDAS/CIVIL对矮塔斜拉桥施工过程进行模拟分析,分析了矮塔斜拉桥在恒载作用下,双非线性对桥梁挠度、内力及应力影响,提出了有益建议,可为同类桥梁的设计与施工控制提供一定的参考。
Taking the short tower cable-stayed bridge for the enginering background,Considering the influence of system transformation and the nonlinear effect of the short tower cable-stayed bridge in the construction process,Using the special bridge calculation software MIDAS/CIVIL simulation the con-struction process of the short tower cable-stayed bridge.Analysis of the short tower cable-stayed bridge under dead load,double nonlinear influence on the deflection,internal force and stress.Put forward the useful suggestions,may provide some references for design and construction of the Similar bridge.
