摘要
宽肩台式无人工护面块体的抛石防波堤是一种新型结构的斜坡堤，它是靠在波浪长期作用下最终形成的动力平衡断面来防浪的。大连北良粮食中转港系世界银行贷款建设的项目，该港的防波堤采用了宽肩台式结构，这在我国尚属首例。本文为该港宽肩台式防波堤设计方案稳定性的试验研究成果。文中详细阐述了宽肩台式防波堤在不规则波及规则波作用下冲刷剖面的演变过程及其在设计条件下最终形成的动力平衡断面。该项研究除通过试验选择了满足设计要求的初始断面设计方案外，还对宽肩台式防波堤稳定性的试验方法、试验程序等进行了探讨，并取得了一些初步成果。
The broad-shouldered platform riprap breakwater, without artificial protective surface piece, is a new type sloping breakwater. It depends on the dynamical equilibrium section formed by long time wave force action to provide wave protection. In Dalian Beiliang food transfer port project loaned by the World Bank, this kind breakwater is adopted and it is the first use in our country. This paper provides the stableness testing study result of the design plan of the breakwater. The developing process of the breakwater surface scouring with the action of irregular wave and regular wave, and the dynamical equilibrium section under the design condition are discussed in detail. Besides choosing the beginning section design plan meet the designing requirement through experiments, the paper probes into test method, and test procedure of the broad-shouldered riprap breakwater's stableness, and gets some useful initial results.
