中文摘要	圆形断面管道在工程中的应用十分广泛。排水管道设计中,常需要计算某一充满度下非满流的流量及流速。根据水动力学基本原理及数学分析方法,提出了充满度与流量比、流速比的统一解析表达式,并对圆形断面管道流独特的水力特性进行了研究分析。采用试验手段,进一步对圆形断面管道无压均匀流流量—充满度的非单一性、水深—流速关系进行了分析研究,进而提出了更为合理的表达式。; The pipelines with circular section are used widely in the practical engineering. In the sewer design it is often necessary to determine the flow discharge and velocity under the partially filled condition. Based upon the principle of hydrodynamics and mathematical analysis, the uniformly analytical expressions of the ratios of flow discharge and velocity to those of fully filled respectively are presented, and the unique hydraulic characteristics of flow are fully analyzed. Furthermore, the dyadic characteristics of discharge-fullness and the relationship between depth and velocity are experimentally investigated fully. Based upon the results the analytical expressions are presented.; 国家自然科学基金(50378049)资助。
