摘　　要：斜立管排水管的应用是解决建筑特殊造型的排水方式的一种尝试和创新。结合建筑独特造型,进行排水立管布置方式比选,确定采用排水斜立管的可行性。通过BIM模型分析斜立管的空间布置,选择最佳排水支管接入方式和角度。进行气液两相流仿真模拟,先开展相同高差条件下的竖直排水立管模拟,校验模拟数值与规范标准值的一致性,然后进行设计秒流量下的斜立管模拟,通过最不利点10 ms采样周期的中频波动气压最大值,来确定斜立管排水管的排水能力。The application of inclined vertical drainage pipes is an attempt and innovation to solve the drainage problems of special architectural shapes.Based on the unique architectural design,compare and select the layout of drainage risers to determine the feasibility of using inclined drainage risers.Analyze the spatial layout of inclined pipes through BIM models,and select the optimal drainage branch pipe connection method and angle.Conduct simulation of gas-liquid twophase flow,first simulate the vertical drainage riser under the same height difference conditions,verify the consistency between the simulated values and the standard values in the specifications,and then simulate the inclined riser under the design second flow rate.Determine the drainage capacity of the inclined riser drainage pipe by measuring the maximum value of the intermediate frequency fluctuation pressure at the most unfavorable point with a sampling period of 10 ms.
