開水路流れに設置された橋脚周辺の水理特性について (1)

Abstract

Hydraulic characteristics around various types of flow obstructions is a problem of continuinginterest. Many investigators have published results on the various aspects of this problem inthe past, particularly on the local scour around bridge piers.The present study is concerned with local scour around single cylindrical pier or plural cylin-drical piers arranged in various types under the condition of clear water scour. In the case ofsingle cylindrical pier, the variation of scour depth with time is investigated experimentally toobtain a formula. On the other hand, in the case of plural cylindrical piers, the effect of arrange-ment of piers on the scour characteristics is investigated mainly.
