震损情景下人员疏散可视化模拟

地震发生时,其引发的下落碎片会影响人员疏散速度甚至造成人员伤亡,但现有的研究通常未考虑地震诱发的下落碎片对人员逃生的影响.因此,综合考虑地震作用下人员恐慌心理和下落碎片覆盖率等因素,对传统社会力模型的参数进行修正,并对云南大学力行楼进行人员疏散可视化模拟,提出一种"先避难,后疏散"的疏散方案.模拟结果表明:在考虑这些因...

Visual simulation of evacuation under earthquake damage scenarios

When an earthquake occurs, The evacuation speed will be affected by the falling debris caused by the earthquake, and even cause casualties. However, the impact of earthquake-induced falling debris on personnel escape has not been considered by existing research. Therefore, this paper comprehensively considers factors such as the panic psychology of the people under the action of the earthquake and the coverage rate of falling debris, revises the parameters of the traditional social force model, and conducts a visual simulation of the evacuation of people in the Lixing Building of Yunnan University, and an evacuation plan of "evacuation first, evacuation later" was proposed. The simulation results show that, considering these factors, the results are more in line with the evacuation activities of people in real earthquake scenarios. The evacuation plan proposed in this paper can provide certain guidance and assistance for disaster evacuation drills and evacuation routes.
