Investigation and analysis for the use and light environment of air-raid shelters in Chongqing
The current world pattern is relatively stable,and the reconstruction and utilization of civil defense facilities in peaceful times has become a very important topic for governments and related research fields in many countries.Due to the wartime legacy,Chongqing has a large amount of air-raid shelters,and these air-raid shelters have been reused and transformed into diverse spaces.Natural light is closely related to human health,but the air-raid shelters embedded in the mountains and hidden underground are dark and damp,and it is difficult to receive enough natural light indoors,so introducing natural lighting is an important factor to be considered for air-raid shelter renovation.Under this background,this paper studied and analyzed the distribution characteristics of civil defense shelters in the main urban area of Chongqing through literature research,questionnaires,and on-site measurement,and carried out a typology classification of existing air-raid shelters,evaluated the renovation status,measured the illuminance of samples,and summarized the influencing factors of natural light environment in air-raid shelters in Chongqing.The air-raid shelters in the main urban area of Chongqing are mainly concentrated in Yuzhong Peninsula,Shapingba District,and Jiulongpo District,and their distribution is affected by population,transportation,topography,and rivers.The types of air-raid shelters are diverse,and the cross-section width of most air-raid shelters is 3 000-4 800 mm,and the layout is single,parallel,branched,and grid-like.The functions of renovated air-raid shelters include commerce,catering,warehousing,municipal administration,and culture.Experimental data show that the internal illumination of air-raid shelters is generally low,and gradually decreases with the increase of depth.The illumination on both sides is greatly affected by natural light and shelters.The introduction of natural light helps to improve the comfort and efficiency of space.
