ABSTRACT

The present study focus on the wave-structure interaction of a caisson type offshore intake well with the regular waves. A 1:20 scale model is experimentally investigated with and without curtain wall in the shallow wave basin for its hydrodynamic responses like wave run-up, rundown, and free surface water oscillation inside the well. The wave run-up and rundown on all the faces record maximum when the scattering parameter (ka) is minimum. Moreover, the increase in relative wave height (H/d) results in an increase in the run-up on the seaward and shoreward faces. Besides, the free surface oscillation at the inlet and pumping chambers measures maximum when ka is minimum, and the influence of H/d keeps on reducing when the ka approaches the maximum value. The insertion of the curtain wall reduces the free surface oscillation at the pumping chamber when the relative water depth (d/L) ranges from 0.21 to 0.36.

摘要

目前的研究重点是沉箱式海上取水井与规则波浪的波浪-结构相互作用。实验研究了一个 1:20 比例模型在浅波盆中有和没有幕墙时的水动力响应，如波浪上升、下降和井内自由地表水振荡。当散射参数（ka）最小时，所有面上的波浪上升和下降记录最大。此外，相对波高 ( H/d ) 的增加导致向海和向岸面上的爬升增加。此外，入口和泵送室的自由表面振荡在 ka 最小时测量最大，H / d的影响当 ka 接近最大值时继续减小。当相对水深 (d/L) 为 0.21 至 0.36 时，幕墙的插入减少了泵室的自由表面振荡。
