  1. ( 3 ) through dimension analysis, factors that affect the flow deceleration through frames are discussed. based on flume experiments, this study indicates the velocity near the bed decreases as the l / h increases, and the l / h decreases, the influence of frames height on the effect of velocity near the bed is not distinct ( 4 ) by 2 - d mathematical model, patterns of flow through frames are analyzed and the influence of different frame formations on the protection zone is researched, mean velocity in vertical decreases and protection zone enlarges as the l / h, b / b and a / h increases

    ( 3 )通過因次分析,探討了四面體框架群減速率的影響因素,並進行了系列水槽試驗,得出:近底流速的減速率隨框架群相對長度l h的增加而增加,隨框架群相對間隔距離l h的增加而減小;框架群高度對近底流速的減速率影響不大,框架群高度的增加主要表現為減速區的增高。
