【摘要】 本文通过物理模型试验和数值模拟方法,对波流共同作用下大尺度垂直圆柱基底周围床面的冲淤形态及最大冲刷深度进行了研究。基于试验数据,利用线性拟合方法给出了最大冲刷深度表达式。采用数值计算绘制的冲淤形态图与模型试验实测的冲淤形态图比较。吻合较好。采用公式预测波流共同作用下大直径圆柱基底周围床面的最大冲刷深度与试验实测数据比较,误差在30％以内．更多还原

【Abstract】 This paper investigates the scour pattern and the largest scour depth around the foundation of the large diameter vertical cylinder in wave-current coexisting field through physical model test and numerical simulation. Based on the physical model test data and the linear recurrence mothod, a formula of the largest scour depth around the foundation of large diameter vertical cylinder has been developed. The scour patterns plotted by numerical calculation coincide reasonable well with the laboratory data of model test The discrepancy of the largest scour depth predicted by the formula to the measured data is within 30%.更多还原
