室内水上乐园火灾人员安全疏散评估

由于建筑特殊性、功能多样性和致灾危险性，城市室内水上乐园历来是消防监督工作的重中之重。在进行火灾风险评估的过程中，烟气流动控制、人员安全疏散始终是评估工作的重点。以某室内水上乐园为例，根据消防安全工程学原理，针对不同季节、不同业态、游客行动能力及游乐设施特点等因素，按照最不利原则建立火灾场景模型，利用烟气层温度、CO浓度等控制性指标，对烟气流动和人员疏散开展定性与定量相结合的模拟分析，为城市室内水上乐园及相似的大跨度、大空间、多业态场所开展火灾风险评估提供参考。

Assessment of personnel evacuation safety in indoor water park

Urban indoor water park has always been the top priority of fire supervision because of its architectural particularity, functional diversity and disaster risk. In the process of fire risk assessment, smoke flow control and personnel safety evacuation are always the key problem of the assessment. Taking an indoor water park as an example, according to the principle of fire safety engineering and the most unfavorable principle, considering the different seasons, business formats, action ability of tourists and characteristics of amusement facilities, the fire scene model was established. Through the control indexes such as the height of flue gas layer, the concentration of CO, the qualitative and quantitative simulation analysis of flue gas flow and personnel evacuation was carried out. Combined with the results of fire risk assessment, references for the fire risk assessment of urban indoor water park and other places with special functions, large span, large space and multiple formats were provided.
