Study On The Design Of The Accessory Space Of Urban Bridges Across Rivers

Cross-river bridges are the main channel connecting the space on both sides of the urban road network,and as the intersection between the cross-river bridges and the city,the accessory space of the cross-river bridges also plays the role of integrating the surrounding urban environment with its special spatial form and characteristics,which is the unity of space and function.With the progress of science and technology and the continuous improvement of material entities,the design of accessory space of bridges has received more and more attention and concern.This paper combines typical case studies at home and abroad,takes Wuhan,a city where the Yangtze and Han rivers meet,as an example,and divides the city area where the bridge is located,compares the development and evolution of the appendage space design of Wuhan’s cross-river bridges,and after an in-depth investigation and analysis,finds the current situation and problems in the use of the appendage space of Wuhan’s cross-river bridges,and finally proposes design principles to be followed and design methods to be used in the design of the appendage space of cross-river bridges.Finally,the design principles and design methods that should be followed in the design of the appendage space of the cross-river bridges are proposed,hoping to provide some reference for the design of the appendage space of cross-river bridges in the future.First,the design of bridges and their appendage spaces is closely related to the development and construction of the city;second,the design focus of the appendage spaces of bridges varies according to the location of the bridge in the city;third,the current situation of the design of the appendage spaces of Wuhan’s cross-river bridges has the problems of ignoring the pedestrian needs and the limitations of independent work;fourth,the design of the appendage spaces of bridges should introduce the concept of synergy to solve the existing problems;fifth,on the basis of the theory of synergy,it is possible to Fifth,based on the theory of synergy,the design means of CI can be applied to the comprehensive planning and design of the appendage space of cross-river bridges;Sixth,the design of the appendage space of bridges should not only focus on the planning and design of the appendage space,but also on the redesign of the appendage space.
