摘　　要：通过对圆形断面无压流水力计算公式进行适当变换,建立了在一定流量条件下求解其正常水深与临界水深的数学模型,并针对实例采用Matlab语言进行了编程计算,其过程简单,结果精确。Through appropriate transformation of the hydraulic calculation formula of round tunnel without pressure, normal depth and critical depth calculation models under certain charges are established in this paper. Additionll, Matlab language is used to pro gram for an application example. The programming process is simple and the calculation results are exact.
