The Research On The Design Of Reconstruction And Expansion Of Small And Medium-sized Terminal

China is the world’s fastest-growing civil aviation traffic state now, expand existing airport capacity to become China’s civil aviation the main problem at present. "Twelfth five-year" period, the increase of the airport and the reconstruction and expansion ratio of rise is significant. The development of the airport in China have periodic characteristics, follow the principle of "planning, installment construction". Terminal layout, passenger processes, office facilities, service facilities require periodic upgrades, replacement and reconstruction. The the large-scale plane, passenger increasing, on the other hand, change the way of growth, the landside traffic, and the application of new theory and new technology and new materials are triggered terminal expansion.Based on the existing terminal design theory, this paper focus on the expansion and reconstruction of small and medium-sized terminal design research. Through analyzing the basic features of small and medium-sized airport terminal and a summary of the characteristic of reconstruction, combining research instance, puts forward the expansion and reconstruction strategy of our country small and medium-sized terminals and verified through the design practice.Paper first elaborates the research background related research status inland and abroad are summarized, put forward the research content and rational research framework. Second, this paper summarizes the present and future development of small and medium-sized airport, the classification of small and medium-sized airport and transport processes. Analysis the function of the layout, structure and passenger process of the small and medium-sized terminal,and summarizes the background and basic characteristics of terminal expansion and reconstruction. Third, in this paper, the typical projects of small and medium-sized terminal in our country has carried on the research analysis, starting from the background and basis of expansion and reconstruction, analysis terminal design mode and the way of expansion and reconstruction, and put forward the theory to evaluate together before. Fourth, on the basis of theory research and example research,summarizes our country small and medium-sized terminal design strategy of the reconstruction.The eight kinds of conditions in three premises put forward different strategy. Finally, analysis the yulin yuyang airport projects with detail, put forward the expansion and reconstruction strategy of further validation of the above.The purpose of this paper is to explore the high efficiency, high quality of small and medium-sized terminal expansion and reconstruction design approach, and improve the rationality,scientific and suitability of the reconstruction project, and hoping to provide reference for future projects.
