通过试验,本文对透空式空箱式防波堤的性能给予评价。认为:透空式空箱堤的消浪效果较好,其稳定重量可减轻10%—15%,开孔率为0.3左右,横孔和竖孔形式差别不大,双L型顶墙效果较好,可进一步考虑其施工的可能性。

The authors in their paper evaluate the properties of perforated box caisson breakwaters on the basis of their experiments and studies. The authors hold that, the perforated box caisson breakwaters possess a better wave—dissipation effect, the weight of stability can be reduced by 10%—15%, the ratio of orifices is about 0.3 and no much difference is noticed between caissons with transverse holes and those with vertical holes, twin—L shape parapet walls can provide a better wave protection, and the possibility of construction of such breakwaters should be further studied.
