摘要
通过对多种影响大型公共建筑安全因子进行探讨,建立了考虑环境信息的动态参数模型—扩展的元胞自动机人员疏散模型。并应用模型对突发公共安全事件的不同条件进行设定,对建筑不同位置、不同的场景进行非正常情况下的疏散模拟,探讨突发事件发生后可能的疏散过程,提出大型铁路客站安全评估方法。
The railway station in China is transformed into a comprehensive transportation hub of the city from t the original single function waiting mode. The indoor space is large and crowded, which brings a huge challenge for public security guard. Computer simulation, using iterative calculation way to simulate real crowd evacuation scene, has a great application value. Cellular automata model is more appropriate to be used in large public buildings evacuation simulation. This paper discussed a variety of large public construction safety factors, established a dynamic parameter model considering the environment information-extension cellular automaton model. Application model on different conditions of public safety emergencies, simulated different scenarios for abnormal situations. Possible evacuation process was discussed. Proposed safety assessment method for large railway stations.
