设置疏散避难区解决疏散宽度不足的探讨

Discussion of setting evacuation shelter area to compensate the inadequate evacuation width

分析地下大型商场超市安全疏散存在的不利因素。针对地下大型超市疏散通道过长和疏散宽度不足的问题,结合有关消防技术规范和日常工作的实际,进行分析和初步的技术论证,并提出设置疏散避难区的对策。以某地下大型超市为例,应用该方法设置疏散避难区,并进行性能化设计论证其有效性。

The disadvantages of underground shopping mall and supermarket evacuation were analyzed.Combining the related standard and actual daily work,the problems of evacuation path being too long and evacuation width being inadequate in underground large supermarkets were analyzed and technically demonstrated,and countermeasure of setting evacuation shelter area was put forward.Taking an underground large supermarket as an example,the method was utilized to set the evacuation shelter area,and performance based design verification was carried out to prove the effectiveness.
