摘要
为建立适用于我国高层民用住宅特点的紧急疏散模型,为评价高层住宅建筑安全性、指导人员逃生提供科学依据。通过问卷调查和实际观测,分析家庭疏散对象的心理特征,对传统紧急疏散模型进行优化,提出以家庭为单位的集群紧急疏散模型,并进行仿真。仿真模型以社会力模型为基础,通过分析和计算家庭内部成员与外部人员2种不同的"社会心理力",进而体现集群疏散的宏观特征。仿真结果分析了家庭集群疏散与传统紧急疏散,这2种情况下主要交通参数的差别,论证了家庭集群疏散模型的科学性和合理性。
In order to evaluate the safety of high-rising building,establish a cluster evacuation model and provide a scientific basis for evacuation,the psychological characteristics of family evacuation were firstly analyzed through questionnaire survey and observation.Then a family-based cluster emergency evacuation model was proposed by optimizing the traditional evacuation model.At the same time,simulation was conducted by adding the social force model into the optimized model and then calculating the two different social psychology forces of family members and outsiders,which embodies the microscopic characteristics of cluster evacuation.The simulation analyzed the differences of main traffic parameters under family cluster evacuation and traditional emergency evacuation,and demonstrated the scientificity and rationality of family cluster evacuation.
