摘　　要：矩形、圆形及城门洞型涵洞(或涵管)在工程中应用非常广泛。按照明渠均匀流计算其最大泄流量时,设计者根据经验一般会按照水流充满涵管的状态进行计算。实际上,对于上述各种形状的涵洞,在明渠均匀流状态下,其最大泄流量并不都是发生在满管流的状态。论文就此进行了分析。Box, circular and arch shaped culverts are widely used in hydraulic engineering. To calculate the peak discharge of culverts for uniform open channel flow, designers usually assume that culverts are completely filled with water based on experience. In reality, under uniform open channel flow conditions, the peak discharge of culverts of above mentioned shapes might occur when the culverts are not full. This paper analyzed this condition.

关 键 词：涵洞 明渠均匀流 最大泄流量
