摘　　要：针对明流水力计算中人工渠道均匀流水深h0和临界水深hk用试算法和查图法计算繁琐,查算精度较低等问题,本文提出了迭代计算方法,并完整地介绍了几种常用规则过水断面明流的均匀流水深和临界水深的迭代计算关系式和算例。In order to solve the troubles and the problem of lower precision in computation of uniform flow depth （ h0 ） and critical depth （ hk） of open channel flow with the trial method and diagram checking method, an iteratlve method is introduced herein a- long with some complete calculation cases and formulas concerned for the calculation of open channel flow through normal regular sections.
