摘要
为保证荷麻溪特大桥在施工过程中结构的受力和线形符合设计要求,运用ANSYS软件对施工过程进行数值分析,介绍了预应力的处理方法、单元生死特性的应用,计算出的桥梁各断面应力、索力和桥梁线形与测量结果十分接近,说明使用ANSYS可以很好的对部分预应力混凝土斜拉桥施工过程进行仿真分析。
In order to meet the designed requirements of the Hemaxi Bridge in structural strength and line-arity,a numerical analysis is made of the construction process with the ANSYS software in the paper,with the pre-stressing methods and the characteristics of the critical Element introduced,It is found that the sectional stress, cable force and linear shape of the ANSYS analysis results are totally in agreement with the measured on-site results, which proves that the ANSYS software can be used to simulate and analyze the construction processes of partially cable-stayed bridges.
