摘要
以紫阳汉江特大桥主桥为例,分析了悬臂浇筑时预拱度需要考虑的因素与影响线形的误差因素,通过对两种施工预拱度的计算分析方法进行对比分析,得出了优化的施工预拱度计算方法。
Taking Ziyang Hanjiang bridge as an example,this paper analyzes the precamber when the cantilever casting factors to be considered and the error factors of linear. Through the comparison of the two kinds of calculation and analysis method of prearch degree,the method of optimizing the construction precamber is obtained.
