摘要
介绍了斜拉桥施工过程的索力确定与优化方法。精确考虑结构的几何非线性、混凝土的收缩徐变等效应,对大跨度混凝土斜拉桥施工全过程进行仿真分析与研究。编制了相应的计算程序,用于分析湖南某大桥,获得了较好的结果,为该桥的施工监控提供了理论依据,确保了该桥的顺利合龙。
The determination and optimization of the cable forces for construction sequences of cablestayed bridges has been studied. Considering the influence of geometric nonlinearity, shrinkage and creep of concrete, a method is introduced, it can solve emulation analysis for construction sequences of long-span cable-stayed bridges. A program is developed upon this method. Engineering application of the developed program in a bridge of Hunan demonstrates the feasibility of the proposed method.
