城市高架桥无支架施工研究分析

Study and Analysis on Construction of Urban Viaduct without Supports

摘要:

近年来，随着城市化进程的不断推进，城市人口呈现日益增多的趋势，机动车保有量显著提升，城市交通日益拥堵。高架快速路由于具备占地小，立体化交通功能强大等优点而被广泛采用。而城市高架桥施工对现状交通必然存在一定程度的影响，因此开展高架桥结构无支架施工设计的研究，旨在探究出不同结构形式及施工方案在高架桥建设中的适用特点，可为今后类似结构设计和施工提供参考。

Abstract:

In recent years, the urban population has shown an increasing trend due to the continuous development of urbanization. In the meantime, since the number of motor vehicles increases with the population, the congestion of urban traffic is getting serious. The elevated expressway is widely used because of its small land occupation, powerful three-dimensional traffic function and other advantages. The construction of urban viaducts will inevitably have negative influences on the current traffic. As a result, it is necessary to carry out the research on the construction and design of the viaduct structure without supports, which is aimed at the study on application characteristics of the different structural forms and construction schemes in the construction of elevated bridges. The reference can be provided for the design and construction of the similar structures in the future.
