摘要
通过波浪水槽系列模型试验对岛礁地形上的波浪破碎位置进行试验研究。试验中将岛礁地形概化为向海陡坡与水平平台相连接的模型,研究3种陡坡(1∶1. 5、1∶3和1∶5)、3种相对水深(0. 1、0. 17和0. 24)下的波浪破碎位置。结果表明,波浪相对破碎位置与Irribarren数、礁坪相对水深以及前坡坡度有关,且随Irribarren数和相对水深的增大而向岸侧移动,随坡度的变陡而向海侧移动。同时,也给出了波浪破碎位置计算方法。
The wave breaking positions of the island reefs were tested by a series of wave flume model tests.In the experiment, the reef topography was generalized to the model connecting the steep slope to the horizontal platform.The locations of the wave breaking under 3 kinds of steep slopes( 1∶1. 5,1∶3 and 1∶5) and 3 relative water depths( 0. 1,0. 17 and 0. 24) were studied.The results show that the relative position of wave breaking is related to the number of Irribarren,the relative water depth of the reef flat and the fore-reef slope.The breaking position moves toward the shore with the increasing of Irribarren number and relative water depth,but toward the sea side with the steepness of the slope.Finally,the calculation method of wave breaking position was also given in this paper.
