摘要
针对分层流体中非波导情况的荷载问题,就密度剖面为两间断分层和三层模式的情况,分别利用势流理论解析解和分段构造的垂向结构方程解,得出了对应波场的速度和作用于垂直桩柱上的荷载分布。结果表明,非波导情况下的波场具有与波导情况及表面水波情况所不同的特性。由于波频较高,其所形成的荷载比波导情况为大,而且在流场内部存在大的波力和切向速度间断。
In this paper, the wave load problem in the stratified fluid for the case of non-wave-guide is discussed. With conditions of two disconnected layers and a three-layer model of the density section, the velocity and load distribution on the vertical stake are obtained for corre- sponding wave fileds. The results show that the wave fileds of non-wave-guide possess different characteristics with conditions of the wave-guide and the surface waves. As the wave frequency is higher, the resultant load is greater than that under the wave-guide condition. Further more, disconnection is found between wave force and shear velocity within the fluid field.
