海堤和护岸的损坏主要是由破碎波引起的波浪冲击造成的。这些冲击力在很短的时间内作用在小面积上，并造成火山口状的形成，当这些力瞬间传递到堤坝覆盖层的裂缝侧壁或通过连接进入和下面的护岸。本文介绍了冲击力的研究结果。现场数据和实验室数据的比较证明了相当大的差异，这必须主要由不同的原型和小规模的条件下，在破碎波的空气截留。现场和小比例尺模型的数据都强调，堤坝或护岸的坡度首先对冲击力的频率和大小负责。此外，冲击力的影响，证明了与缝石护坡的稳定性的调查结果。
Damages on seadykes and revetments are mainly caused by wave impacts due to breaking waves. These impact forces act on small areas for a very short time and cause crater-like formations, when the forces are transmitted instantaneously to the side-walls of cracks in the cover of dykes or through joints into and below revetments. In this paper the results of investigations on impact forces are presented. A comparison of field data and laboratory data proves considerable differences, which must be explained mainly by the different air entrapment for prototype and small-scale conditions in the breaking waves. Both the data from field and small-scale model emphasize, that the slope of the dyke or revetment is responsible at first for frequency and magnitude of the impact forces. Furthermore the effect of impact forces is demonstrated by the results of investigations on the stability of stone revetments with joints.
