摘　　要：文章以某小区一房屋发生废水倒灌事件为例,研究水力计算在住宅楼废水倒灌原因分析方面的应用。调查了整个废水排水管线的设置情况、查阅了与之相关的排水管线的设计资料后,运用水力计算方法分别依据设计管线和实际管线的设置工况,计算与事故房屋相连通的排水系统的需排水量(等于系统内卫生器具流出的废水总流量)和排水能力(排水流量),对计算结果进行比较分析后得出引发废水倒灌事故的真正原因。This paper studies the application of hydraulic calculation in cause analysis of wastewater backflow in residential buildings by taking the wastewater backflow incident in a residential building as an example. The setting of the whole wastewater drainage pipelines was investigated,and the design data of the corresponding drainage pipelines were consulted. After that, the hydraulic calculation method is used to calculate the required drainage volume( the total wastewater flow from the sanitary equipment in the system)and the drainage capacity( the drainage flow) of the drainage system associated with the accident house according to the design and the actual pipeline setting conditions respectively. After comparing and analyzing the calculation results,the real cause of the accident caused by the wastewater backflow is obtained.
