摘要
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:在考虑这些因素的情况下,其结果更加符合现实中地震场景的人员疏散活动,所提疏散方案可以为灾害疏散演习和疏散路径提供一定的指导和帮助。
When an earthquake occurs,The evacuation speed is affected by the falling debris caused by the earthquake,and even causes casualties.However,the impact of earthquake-induced falling debris on personnel escape is not considered by existing research.Therefore,considering the factors such as people's panic psychology and falling debris coverage under the action of earthquake,the parameters of the traditional social force model were modified,the visual simulation of personnel evacuation was carried out for the Lixing building of Yunnan University,and an evacuation scheme of“first refuge,then evacuation”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 proposed evacuation plan can provide certain guidance and assistance for disaster evacuation drills and evacuation routes.
