Study On The Design Of Enerance Space Of Urban Underground Commercial Buildings

The development and utilization of underground space has become the strategic choice that anti the crisis such as population increase, land-shortage, environmental pollution in the 21st century all over world.And the underground floor of commercial buildings has experienced an unprecedented development, and gradually become an important aspect of the development and utilization of underground space.The entrance of the underground space is an important component of the underground commercial buildings. The quality of the underground constitutes the first impression of commercial buildings. As the transition and integration of intermediate points of urban space and underground commercial space, it is also parts of urban public space, it assume the duties of the lives of urban public. How to create a suitable entrance to the underground space for commercial buildings that coordinate the development of underground space is what we will face to.In this paper, at first,It defined the type and sum up the elements of the entrance space ,and analyzed the composition and characteristics in detail, it provided the basis for the entrance of the space for further analysis to support the theory. Then, analyzed the entrance of the underground space for commercial buildings from people and cities in use .In urban areas, the entrance of the space should meet the urban transport function and landscape requirements, etc.; in the people's ues,it analyzed the impact of the entrance space commercial buildings between the ground floor of the space environments and the modern consumer psychology, and analyzed the environmental behavior of the entrance of the underground space for commercial buildings in the "human" behavior.Then, in the theoretical analysis, based on the status of the survey combined with the existence of the advantages and disadvantages of the entrance space, proposed the ways and means to establishment an appropriate urban environment and safe , comfortable entrance to the ground floor of commercial buildings, that is, in the entrance of the design of space form, It should be emphasized that the vertical space on the entrance of the transition has no intention and ease of transport, and to identify the areas of security .In order to create an orderly underground shopping and leisure venues to attract more shoppers .Finally, the design of the entrance in Qingdao Donghai Road of the commercial pedestrian street proved the ways and means.
