Demonstration of the Overall Design Scheme for the Reconstruction and Expansion of Guangzhou North Second Ring Expressway
At present,there are few examples of the reconstruction and expansion projects of super multi-lane expressways with more than ten lanes in China,and there is a lack of mature design experience.Due to various control factors such as road network planning,urban land use,schools,and residential areas,the formulation of reconstruction and expansion plans for super-multi-lane expressways located in urban areas is particularly complex.It is necessary to carry out targeted research on the reconstruction and expansion technology of super-multi-lane expressways to support future expressway reconstruction and expansion design work.In this paper taking the ongoing Guangzhou North Second Ring expressway reconstruction and expansion project as a design example,multi-level analysis is carried out,and the formulation and comparison of reconstruction and expansion route plans under complex control factors in urban areas are discussed,which provide some ideas and references for determining the overall plan of similar urban super-multi-lane expressway reconstruction and expansion in future.
