本文介绍透空沉箱插板式消波堤(Ⅰ型和Ⅱ型)的设计及模型试验的初步成果。文中附有图表。本文对反射率、透过率、作用波压力、堤顶喷水与越浪等情况作了分析。试验证明透空沉箱插板式消波堤具有自重轻,消浪性能比较好,反射率和透过率低,越波量小等优点。 This article introduces the design and model test of the open caisson pluggable breakwater (type I and type II). Text attached to the chart. In this paper, the reflectivity, transmittance, the role of pressure wave, water jet and overtopping conditions were analyzed. The test shows that the open caisson plug-in type breakwater has the advantages of light self-weight, good wave-eliminating performance, low reflectivity and transmittance, and small wave number.
