Research On Interaction Effect Of Thermal,light And Acoustic Environment On Human Comfort In Waiting Area Of High-speed Railway Station

As an important type of public buildings,the high-speed railway station has the characteristics of large space and dense flow of passengers.Currently,under the concept of "Station-City Integration",the high-speed railway station has transformed from a simple city portal to an urban complex,with more diverse internal functions and more complex indoor physical environment.With the increasingly close relationship between high-speed railway station and urban life,as well as the improvement of people’s comfort demand,the space quality and indoor environment quality of high-speed railway station waiting hall have also attracted more attention.Taking the waiting area of ordinary passengers in the waiting hall of high-speed railway station as the research object,this study explores the comprehensive influence of its architectural space elements and physical environment on the perception of passengers’ environmental comfort,and puts forward suggestions on architectural space optimization and indoor physical environment regulation.The research steps and main research contents are as follows:(1)Dismantling and evaluation of the architectural space elements of the waiting hall of the high-speed railway station.The space design elements of the waiting hall are disassembled,and the important spatial elements which have more influence on the overall environmental perception of passengers are selected.Then,a questionnaire was established through Semantic Differential method and distributed to passengers in many large-scale high-speed railway stations in China to understand the passengers’ evaluation of the space elements of the waiting hall,and introduced the IPA method to analyze the necessity of improving the space elements,and propose the optimization of the waiting hall space design.(2)Physical environment measurement and passenger comfort evaluation of waiting hall.Two large-scale high-speed railway station waiting halls in Cold Climate Zone and Hot Summer and Cold Winter Climate Zone are selected to carry out objective physical environment measurement and subjective passenger comfort survey to understand the basic conditions of environmental quality and passenger comfort perception evaluation of waiting hall.Finally,the interaction of multiple physical environment factors on passenger comfort perception in the real scene of waiting hall are demonstrated.(3)Experimental study on the interaction between the architectural space and physical environment of waiting hall.Taking the space elements and physical environmental factors of the waiting hall as the experimental variables,the environmental simulation experiment is carried out to explore the comprehensive effect of the two factors on the evaluation of human comfort and their influence on the objective physiological indicators of the human body.The interaction between building space and physical environment factors on the comfort of passenger environment obtained in this study.The conclusion can provide quantitative reference for the optimization design of high-speed railway station building space,besides,it can provide data for improving the indoor environmental quality of high-speed railway station waiting hall and improving the comfort of passenger environment.This study is of great significance to improve the space quality of the waiting hall of high-speed railway station and optimize the travel environment of high-speed railway.
