Abstract:The Qingdao Shandong Road - Anshan Road Three-dimensional Reconstruction Project is located in the old urban area of Qingdao, in which the elevated interchange ramp, ground bus terminal, underground social parking and subway access are set up. The construction of the project has comprehensively alleviated the multiple problems in the area, such as traffic congestion, inconvenience of public transportation, and insufficient supply of parking facilities, which is a comprehensive transportation hub project with multiple transportation functions and intensive land utilization. The surrounding facilities of the project are mature, but the construction conditions are complex. Through making full use of the space under the elevated ramp bridge and utilizing the underground space deeply, the comprehensive traffic function of the city can be maximized within the limited space, and the efficient and seamless transfer of bus, P + R parking and subway is achieved, which can provide some reference values for the urban renewal of the old urban areas.
