摘要
空间实体模型和空间梁模型在桥梁的计算分析中都有较广泛的应用,以澳门—凼仔第三大桥正桥部分的空间三维仿真分析为例,分别采用上述两种方法进行了对比计算分析.结果表明:两种模型的计算方法有较大的差异,但其计算结果的差别在工程允许范围之内.在此基础上,进一步总结了上述两种方法的主要优缺点.
The solid model and spatial beam model are widely used in bridge computation and analysis. Simulation analysis of the main bridge portion of Macao-Taipa 3rd bridge with the two models is given as an example. Although the two models are different, the results show an allowed difference. The advantages and shortcomings of the two models are compared and summed up based on the results.
