Abstract:In recent years, with the rapid development of engineering construction in China, the problems encountered in the urban construction become more and more complicated. Based on an example, the design of Suzhou Xinggang Street Tunnel up-crossing the interval node of Metro Line 1 is introduced. How to manage the design process of similar engineering nodes in the mode of design planning, design input, design control and design output is explained. By clarifying the design process of key engineering nodes, the node design work can be carried out more precisely, comprehensively and effectively in order to improve the design quality of the node.
