基于太阳光紫外线和风环境模拟的武汉雷神山医院防疫工作规划分析响应

利用网络开放数据、Auto CAD 2008、众智日照分析7.5、PHOENICS 2011建立雷神山医院及周围一定范围内建筑三维模型，实现太阳光紫外线和风环境仿真模拟并进行叠加分析，为建立防控预警机制奠定基础。结果表明：该医院整体室外地面高度处太阳光紫外线日照环境较好；冬季和春季工况下隔离医疗区室外人行高度处整体风速欠佳；医护生活区和综合后勤区冬季工况下风速利于污染物自然消散，春季欠佳；冬季和春季工况下医护生活区和后勤保障区建筑表面风压差整体有利于室内自然通风；因此仍需做好日常清洁消毒和重点防疫工作，并建议对病毒进行室外检测。

Analysis and response of COVID-19 prevention planning based on ultravioletand wind environment simulation in Wuhan Leishenshan Hospital

Using network open data, Auto CAD 2008, Sun Analysis 7.5, and PHOENICS 2011, a 3D model of buildings in Wuhan Leishenshan Hospital and its surrounding areas are established to perform the simulation and superposition analysis of sunlight ultraviolet rays and wind environment, which lays a foundation for the establishment of prevention and control early warning mechanism. Results show that the overall outdoor ground height of the hospital exhibits good sunlight and ultraviolet sunshine environment. During the winters and springs, the overall wind speed at the outdoor pedestrian height in the isolated medical area is not good. The wind speed in the medical and nursing living area and the comprehensive logistics area is conducive to the natural dissipation of pollutants in winters; however, it is not good during the springs. Under the working conditions during winters and springs, the wind pressure difference on the building surface of the medical living area and the logistics support area is conducive to the indoor natural ventilation as a whole. Therefore, it is still necessary to conduct daily cleaning and disinfection and perform key epidemic prevention work, as well as the outdoor detection of the virus.
