| Abstract: | An ortho-state flume has been adopted to research the characteristics of local scour about large-scale pile groups foundation in cinquefoil,thus obtaining maximum scour depth,location of maximal deep spot,and scour configuration vertical and parallel to current in pile groups.The results are is compared with those in general collocation.The study results of the cinquefoil pile groups have!been well adopted in construction of Su-Tong Changjiang River Bridge. |
