特大暴雨情况下地下空间类项目排水设计的经验及教训

Experience and Lessons from Drainage Design of Underground Space Projects under Extremely Heavy Rainstorm

摘要:

近年来，极端天气频发，在面对特大暴雨情况下，地下空间类项目因其特殊性，往往水淹危险性高，一旦淹水很容易出现伤亡事件。因此，通过对“7.20”郑州特大暴雨发生时，郑州某地下空间类项目灾后实地走访，了解现场主要进水部位、受灾情况分析后，提出对于地下空间类项目排水设计的经验、不足及教训。

Abstract:

In recent years, the extreme weather occurs frequently. In the face of extremely heavy rainstorm, the underground space projects tend to have a high risk of flooding due to the particularity. Once flooded, the casualties are likely to occur. Therefore, based on the post-disaster field visit of an underground space project in Zhengzhou during the "7·20" extremely heavy rainstorm, the experience, shortcomings and lessons for the drainage design of underground space projects are proposed after understanding the main water inlet parts and disaster analysis.
