Underground Commercial Street Systems Design

Based on the viewpoint of system theory,the constituent elements of underground commercial street is analyzed and the design analysis of the elements in the system is also performed in this paper. The study have shown that:Underground Commercial Street system consists of environmental systems and functions of the system components.Environmental systems include a ground system, exit and entrance transitional space, various factors of underground systems.Functional systems is composed of transportation, commercial and functional facilities. Ground space environment should be designed to comply with the principle of overall planning of urban construction,make the ground environmmt be coordinated with cityconstruction planning and combine with the design principle of regional characteristics.Entrance that is a passage openings between the ground space and underground space is the connecting point of underground commercial street and the surrounding and control personnel or goods through.The design of exit and entrance should overall consider its location, orientation, shape, space design and follow the principle of integrity, the special principle,optimization principle.Underground space design is the core space of underground commercialstreet, and the carrier to realize all of its functions. The system design of underground space includes the overall planning and design of underground space, traffic planning and design, drainage design,safety design and so on.Commercial Street underground system is designed to analyze the overall design of the underground commercial street planning and design,which include ground space design, entrances, underground space design.The above design principle and method had been verified by Huaihua Center Street Underground Commercial Street project and some suggestions with certain reference value were proposed for innovative development model and system design of underground commercial stree in this paper.
