| 中文摘要 | The local scour around a circular pipe undergoing vortex-induced vibration is investigated experimentally in a water flume. The typical characteristic of local scour is analyzed in detail. The influences of initial gap-to-diameter ratio (e(0)/D), the mode of pipe vibration and the sand type on the local scour are discussed. Experimental results indicate that there exists strong intensity of scour when the pipe moves close to the surface of the sandy bed. The vibration of the pipe results in the rapid development of sandy bed's scouring. With the increase of gap-to-diameter ratio the distance between the center of the pipe and the position of the maximum scour depth gets larger. The maximum scour depth does not vary monotonically with the gap-to-diameter ratio, but reaches the largest one at certain gap-to-diameter ratio between the values of e(0)/D = 0 and 2. There is not much difference of the scour profiles around the vibrating pipe between one degree and two degrees of freedom involved in this study. |
