摘要
下承式系杆拱桥无支架施工可以做到通航河流的不断航或少断航 ,具有很大的社会、经济效益。本文针对无支架施工的具体要求 ,对系杆拱桥的构造要求及施工措施进行设计研究。先对骨架的构成方式、各类构件的截面材料形式设计等进行研究分析 ,同时对系杆拱桥无支架施工在设计计算以及施工工艺上的具体要求进行了阐述。
Non?plank construction method of bottom?supported tied arch bridge makes possible of uninterrupt or short time in terrupt of navigation, having very high social and economic benefits. This paper presents a study of the requirements of tied arch bridge constitution and construction from the perspective of design in relation to the specific requirements of non?plank construction. Based on a research analysis of the constitutive pattern of framework and the formal design of the section material of various components, the paper discusses the specific requirements for the designing calculus and construction techniques in the non—plank construction of tied arch bridges.
