过水堆石体渗流及其模型相似

Seepage of Overflow Rockfill and Models Simulation

本文以试验资料为依据并通过雷诺数R_e与阻力系数K＇的关系,提出三个渗流流区的渗流流速系数、渗流流速计算公式及渗流模型相似的比尺效应修正系数。它具有论据正确、概念清楚、形式简单、计算方便等优点,可应用于堆石体渗流计算及渗流模型资料的引伸。

On the basis of experimental data and the relationship between Reynolds number Re and seepage drag coefficient K', formulas for seepage velocity, velocity coefficient and the modifying factor for scale effect of seepage models simulation, for all seepage zones are presented. They can be used in seepage flow calculation and extension of experimental data to prototype.
