Received Date: 20 January 2014

摘要: 潍坊人造沙滩构建于粉砂淤泥质潮滩上,是我国潮滩养滩的首创工程之一,这里潮流速较小,无法起动滩沙,风暴潮的强浪是破坏人造沙滩的主要因素。一期工程抛沙33万m3,一个冬季2次风暴潮侵蚀掉2/3。二期工程延长了东西丁坝,坝头转向中部,沙滩中部增加了T型丁坝,符合丁坝群构建理论,再抛沙30万m3,改善了沙滩的稳定性,半年来监测知无蚀有微淤迹象。

Abstract: The Weifang artificial beach is the first nourished beach constructed on a silty tidal flat in China. The tidal current in this area is too weak to move the beach sand, and the main factor to destroy the artificial beach is the strong wave caused by storm surges. In the first-stage of the project, an amount of 330 000 m3 of sand was filled, and 2/3 of the sand was eroded after two storm surges in the winter. The second-stage of the project extended the groins on both east and west sides towards the middle of the beach. Then a new "T" type groin was built in the middle of the beach. Another 33×104 m3 of sand was nourished on the beach. It has remained stable for half a year.
