摘　　要：排水能力评估是排水管网系统规划、设计、运行和维护的基础。现有的水力性能指数(HPI)主要用于顺坡流动、管顶平接、无泵闸设施等简单树状管网的计算,为适应实际排水管网系统的各种复杂形态和工况,对现有算法进行改进,提出采用综合水力性能指数(CHPI)评估管道排水能力。CHPI由最大全局水力性能指数(MGHPI)、最大自身水力性能指数(MSHPI)和累积水力性能指数(AHPI)加权计算,既能反映管道自身超载程度,又能反映对上游管道超载的影响,同时还能兼顾管道排水能力在时间和空间上的变化,并可应对管道高程的突变。佛山三龙湾某片区8 km^(2)排水管网系统的CHPI评估结果显示,CHPI在实际管网系统排水能力评估中具有很好的应用潜力。Drainage capacity evaluation is the basis of planning,design,operation and maintenance of sewer networks.The current hydraulic performance index(HPI)is mainly used for the calculation of simple tree sewer network that water flows along the slope and pipes is connected at the same top elevation as well as without control facilities.The current algorithm was improved to adapt various complex forms and working conditions of the actual sewer network,and the comprehensive hydraulic performance index(CHPI)was proposed to evaluate the sewer drainage capacity.CHPI is weighted by the maximum global hydraulic performance index(MGHPI),the maximum self hydraulic performance index(MSHPI)and the accumulative hydraulic performance index(AHPI),which can not only reflect the surcharge degree of the pipe itself but also reflect the impact on the surcharge degree of upstream pipe.At the same time,it can also take into account the changes of drainage capacity in time and space,and cope with the sudden change of crown elevation.The application potential of CHPI in hydraulic performance evaluation of actual sewer network was shown by taking an 8 km^(2)sewer network in Sanlongwan area of Foshan as an example.
