2·5 统一(续)就梁式桥而论,要使上部梁式体系与下部墩台之间和谐统一,浑然一体,重点在于墩台造型要简洁并使之与上部结构相协调。因为,梁式桥上部结构形象简单,它仅是单调的连续的长线条,如每个桥墩有几处多余的或装饰性的构造,则下部结构整体地来看,就会显现出线条繁杂,从而,引起上、下部结构间的不统一感。例如:为使用联合架桥机的龙门架而设计的桥墩,其盖梁的两端的悬臂梁部分,伸出一段距离于边梁翼 2.5 CONVERGENCE (CONTINUED) In ​​the case of beam bridges, the harmony and unity of the upper beam system with the lower pier should be emphasized. The emphasis should be placed on the simplicity of the piers and their coordination with the superstructure. Because the beam structure of the superstructure is simple, it is only a monotonous continuous long line. If there are several redundant or decorative structures for each pier, the lower structure will appear as a whole with complicated lines. Therefore, Caused by the structure of the lower part of the sense of unity. For example: for the use of gantry bridge erecting machine designed bridge piers, both ends of the cantilever beam cover part, extending a distance from the side wing wings
