摘　　要：利用正态宽水槽研究梅花形大型涉水群桩基础的局部冲刷特性,得到最大冲深、最深点位置以及桩群内垂向和顺水向的冲刷形态,并与常规形群桩布置引起的冲刷进行了试验对比。其中梅花形群桩局部冲刷的特性和试验结果在苏通长江大桥建设中得到较好地验证。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.
