To The Beijing Capital International Airport As An Example Of The Sponge Urban Construction Technology Application Research At The Airport

The construction of sponge city is a systematic project involving the integration of multiple disciplines.It is one of the important measures in the construction of ecological civilization in China.At the end of 2018,the civil aviation administration of China issued the "implementation opinions on deepening the green development of civil aviation",which clearly proposed to build sponge airport.In the new era,"safe airport,green airport,smart airport and cultural airport" four airports should be integrated into the concept of sponge city construction.This paper firstly starts from the concept of sponge city,analyzes the causes of frequent airport floods,summarizes the advantages and disadvantages of macro systems and specific measures in domestic and foreign literatures,and builds a research background platform on this basis.Then based on the natural geographical conditions,the macro system and concrete measures,and so on typical cases,the airport using sponge urban construction technology at home and abroad combing related theory,the perspective of landscape architecture profession in general design method for sponge airport,approach includes: field present situation investigation,site early analysis of rainfall,drainage and water quality condition has the most direct influence on design sponge;Establish control objectives,which shall be selected according to the water resources situation and economic conditions in the area where the site is located;To classify nature of the construction land partition is to adjust measures to local conditions,to maximize the principle of general construction land can be by way of the bridge and subsidiary green space,building and affiliated green space,park green space and water body unit classification form four aspects,such as sponges,garden sketch,road square,green land,water,and vegetation landscape elements and organic combination of sponge unit;The system of "source stagnant storage and emission reduction,process green control and end ecological regulation and storage and infiltration" is a scientific system integrating the core concept of sponge city--"infiltration,stagnation,storage,net,use and discharge".Green rainwater facilities are arranged by this system.Determine the scale of green rainwater facilities;Intelligent rainwater control system is adopted as the follow-up guarantee link.At last,the paper gives some Suggestions on the application of sponge city construction technology in capital airport.Through research,the next step can be through the dynamic rainfall-runoff simulation of SWMM model software build regional hydrological model to simulate the rainfall test,through the water supply and drainage,pipe rack,geotechnical,and traffic and so on various professional comprehensive coordination,by modification of minimum and get rain flood management to maximize profits,create the rain flood management effectiveness and awareness of the ecological landscape multiple airport landscape.
