| Summary: | 碩士 === 國立成功大學 === 水利及海洋工程學系碩博士班 === 90 === ABSTRACT
The objective of this study is to reduce scour depth of abutments for protecting the bridge. To reduce scour around bridge abutments. Direct methods are used in literature, dealing with abutments-scour problems, such as placed rocks, riprap or flexible mattresses around the abutment foundation. This studies an indirect one that examines the effect of using submerged panels around the abutment.
Experiments conducted in clear-water conditions. The angle of the panel is 135°, the width of the panel is 63 cm, the distance between panel and abutment equal to 0 cm, depth of panel with the submerged water is 1 cm. They can reduce scour depth as much as 99% in final equilibrium.
