| 中文摘要: |
| 高层建筑内人员集中、垂直疏散距离长、烟气垂直方向扩散快,火灾情况比一般建筑复杂,因此需要对高层建筑火灾时安全疏散进行评估。依据高层建筑火灾特点建立基于灰色欧几里德关联理论的疏散安全二级评估模型,分析并建立了适用于二类高层建筑火灾疏散的评估因素集、权重集和参考标准集。该模型通过比较样本序列与安全评估等级序列的灰关联度,得到样本的火灾疏散安全等级,并找出影响安全疏散的关键因素,指出薄弱环节。并通过实例验证了该模型的可行性。 |
| 英文摘要: |
| For the characteristics,the mass evacuee,the long upright travel distance and the fast upright diffusion of fire smoke,of the highrise building fires,the evacuation is different from other ordinary ones.It is necessary to assess the grade of safe evacuation and find the main weak link in evacuation.And an appropriate evaluation model based on twostage grey relational evaluation and the relative Euclid nearness is established.And the factors,weights and evaluation criteria for the secondclass highrise building are analyzed and found.In the process of evaluation,the relational degrees between object series and safety degree series are computed and compared.So safe evacuation degree can be determined and weak links which need to be improved are found out.An example is included to verify the feasibility of evaluation model. |
