近年来，由天然材料制成的自然友好型水工结构引起了人们的关注。基于此，作者对碎石堆堰的基本特征进行了调查，明确了泄流水位特征等。本研究旨在研究碎石丘堰破坏阶段的基本水力特性。结果表明下游堰坡流速和碎石丘堰内渗流力对堰的破坏有影响。
Nature-friendly hydraulic structures made of natural material are attracting attention in recent years. In this point of view, the authors have investigated basic characteristics of a rubble mound weir and clarified the discharge-water-level characteristics and so on. This study was carried out to investigate basic hydraulic characteristics in a failure stage of the rubble mound weir. As a result, it is clarified that the velocity at downstream weir slope and the seepage force in the rubble mound weir have an effect on the failure of the weir.
