摘要
笔者在水槽中用带平台的复坡式海堤进行断面要素和堤前波要素对波浪爬高影响的试验中,发现在某些条件下,随平台加宽,波浪爬高起先减小,然后增加,接着又减小。在试验范围内,增加的数值已达到0.41米。就笔者接触到的文献中,均未提及这一现象,现有的波浪爬高计算公式中也未予考虑,如果忽视,可能会对海堤工程的安全产生不良后果。
In the experiments of wave run-up in a wave flume where the compound cross-section sea dyke is set in,we found that under some conditions the wave run-up will probably go down,go up and go down again through cha- nging the cross-section paramenters and the wave paramenters around the dyke. This phenomenon has not been mentioned in the documents that we have studied,nor has-if been taken into eonsideralion in the formulas for calculation wave run-up.Within the range of the experiments,the incre- ase reached 0.41 m If we ignore this situation,it may probably affect the safety of dykes.
