摘　　要：明渠梯形断面临界水深一般采用计算方法或图解方法，费时费力精度不高，而圆形断面的临界水深只能用计算方法．本文采用简化公式的方法并作成计算表，可以提高计算速度２０倍以上，提高计算精度１０倍以上．Pilot calculation or graphic methods were used to measure the critical water-deep of the open canal's trapezoid seetion, which wasted time and energy and without high precision. This artide gines a simplifying calculation method and designs a schedule which could raise the calculation speed and prceision by 20 times and 10 times respectively.
