床固めの形状とその影響に関する研究
On Form of Ground-Sill and Its Influence
佐々木, 八郎
The problems of the mechanism of flow and the prevention from disasters in the river courses which have continuous consolidation works are studied by the author in this paper, because in them there is a very dangerous phenomenon which is liable to bring forth an eccentric and unstable current. He makes clear experimentally the mechanism of the current, which is applied similarly to some actual cases. This makes it possible for him to seek for an effective form of ground-sills and to decide the suitable work-method by investigating and comparing various forms of improving a river course with each other. He also shows that for the purpose of controlling an unstable current it is necessary not only to satisfy the condition of sectional area of a river but also to keep the ratio of a revetment-height to river-width higher than a certain limit. Besides, he shows the improvement of the form of the Yomase River as an example. The result of this research may be exceedingly useful when it is applied to the reasonable design of the form of ground-sills in the river transporting a heavy bed-material load.
