| During the epidemic,the whole society experienced major shocks,and social development and teaching activities were severely hindered.All buildings that needed to gather were unable to cope with such environmental health problems,including primary school buildings.When the epidemic first broke out,Primary schools were unable to open classes as normal and switched to online teaching.During the normalization of the epidemic,students can go to school normally,but there is still a risk of infection during the school period.Once the epidemic spreads in the school,the consequences will be disastrous.So in the face of such environmental health problems,how to deal with such environmental health problems,we must first understand the transmission mechanism of infectious diseases,which is affected by many factors,such as physical constitution,ventilation,lighting,contact time,safety distance and other factors.For the construction field,only the safety distance belongs to the research category of the construction field,so how can school buildings use the safety distance to deal with such environmental health problems? First of all,it is necessary to understand the classroom space elements that affect the safety distance of students.In ordinary classrooms,different spatial forms,personnel density,entrance and exit width,and spatial elements of seating layout will affect the behavior of students,as well as the safety distance of students.influence.The author uses the method of human flow simulation to study the infection coefficient of middle school students in classroom space and teaching space organization.First,the current situation of the existing classroom space is analyzed,and the spatial elements affecting the pedestrian flow of students in the classroom space are summarized and summarized.The four spatial elements of population density,seating layout,and classroom entrances and exits.Then,according to the surveyed student behavior data,we simulated the impact of these four spatial elements on the infection rate of students in the classroom.According to the influence law of pedestrian flow,a classroom space unit with the slowest infection rate is obtained.Combined with practical significance,the design strategy with the lowest pedestrian infection coefficient in the primary classroom space is refined and optimized to achieve the purpose of optimization.After an optimized classroom unit is obtained,the influence of the teaching space organization on the student infection coefficient is studied.Primary school teaching space mainly includes ordinary classroom space,corridor space,toilet space,teacher office space and stair space.The author uses the method of human flow simulation to study the influence of the location and number of corridors,toilets,teachers’ office spaces and stairs on the infection coefficient of students.According to the simulation experiment results,the design principles of the optimization of teaching space organization are summarized.Refine and optimize the design strategy with the lowest pedestrian infection coefficient in primary school teaching space organization. |
