摘　　要：该研究采用人群疏散模拟来评估山地住区的疏散能力和现行灾害响应预案,从建筑布局形式、路网结构、出入口分布和绿地形态等方面出发,基于模拟结果提出了人群的疏散组织方案。采用线程代理模型开展了人群疏散模拟,基于潜在路径、空间围合程度和绿地空间布局3个变量设立了对比组,分析了总体耗时、累计路径、拥堵特征和不同路段的人数变化,总结了山地空间结构对人群疏散行为和总体安全的影响机制,为中国西南山地城镇住区的疏散安全规划和适灾性设计提供了支撑。Crowd evacuation simulations were used to evaluate evacuation capabilities and disaster response strategies for mountainous neighborhoods. The results were used to develop evacuation plans based on the building layout, road networks, exit distribution and greenery morphology. The simulations used an agent based model for the crowd evacuation simulations with control groups based on potential paths, spatial enclosure degree and green space layout. The simulations give the overall evacuation time, best paths, congestion characteristics and changes in the number of people in various sections. The results also show how the structure affects the crowd evacuation behavior and the overall safety to support mountainous neighborhood safety evacuation planning and disaster response planning in southwest China.
