摘 要: 以学生宿舍楼内人员疏散为研究对象,应用EVACNET4软件和SWJTU/FPE开发的精细网格人员疏散模型对所选建筑物结构进行模化,并预测各种使用状态和各种火灾条件下人员疏散的时间;利用SWJTU/FPE试验室新开发的基于GPS的人员疏散轨迹测试平台,设定3~5种火灾场景,并实际测定各种火灾场景下人员疏散的实际时间;将模拟预测的人员疏散时间和试验测试的人员疏散时间进行对比分析研究,分析比较得出GPS技术在建筑火灾人员疏散研究中应用的准确性和可行性。 Take the evacuation of the dormitory building for reserch. First of all, use Evacnet4 and sophisticated mesh evacuation model developed by SWJTU/FPE to simulate the structure of building, and predict the evacuation time under various use conditions and {ire circumstances. Then set 3--5 types of fire circumstances, use platform of evacuation track testing based on GPS developed by SWJTU/FPE laboratory to test the actual evacuation time under these fire circumstances. Finally, take the testing and modeling time for comparative analysis,then get accuracy and feasibility of application of GPS technology in evacuation of building fire.
