| 摘 要： | 水流夹角对大型、超大型群桩的局部冲刷影响研究至今仍为空白。通过宽水槽试验,对梅花形大型桩群进行了水流夹角对局部冲刷影响的研究,得出不同水流夹角情况下的冲刷形态和由此产生的桩群夹角增深系数。为工程设计及规范中涉及局部冲刷条文的修订提供参考。

| Abstract: | It is still a blank to study the influence of water flow angles upon local scouring around pile groups for large or ultra-large pile groups.Through testing in a large-scale flume,the influence of water flow angles upon local scouring around a quincunx pile group was studied,and the shape of scouring in different flow angles and the resultant enlarging coefficients of included angles in pile groups were obtained,provide references for engineering design and revision of provisions on local scouring in specifications and standards. |
