摘　　要：现行国家消防技术规范对下沉广场能否服务于地下两层,以及避难走道直通地面安全出口的宽度均没有明确规定,导致项目出现了如何确定疏散设计指标的问题。以某大型地下综合体为例,采用数值模拟的方式,分析论证下沉式广场及避难走道通过采取合理调整的方案,可以保证火灾时人员的安全疏散,为该类问题提供参考。The current national fire protection technical specifica-tion has no definite provisions on whether the sinking square can serve two underground floors,or the width of the safe exit of the evacuation corridor directly leading to the ground,which leads to the problem of how to determine the design index of evacuation.This paper,takes a large underground complex as an example,us-ing numerical simulation,analyzes and demonstrates that by reson-able adjustment of sinking square and the refuge walkway,it can en-sure the safe evacuation of the people in the fire and provide a refer-ence for such problems.
