| Bridge piers are sometimes damaged by local scour. Although the problem of local scour around pier has been studied extensively, it has been difficult to estimate local scour depth quantitatively. This study is concerned with local scour around semicylindrical piers arranged in various types under the condition of clear water scour. Through dimensional analysis, it was found that scour depths were relative to Re, Fr, and Ns. In the case of semicylindrical piers, the variation of dimensionless scour depth with dimensionless time (effect of Ns, pier diameter and length, incidence angle) and the variation of scour depth with vortex intensity and resistance are investigated experimentally to obtain a formula. And formula for estimating the maximum depth of scour is obtained. |
