滩涂促淤坝田中淤积三角形研究

The Study of the Triangle Area of Deposit on Net-Shaped Fields

在对条子泥促淤试验工程坝田内外冲淤情况一年多的观察与测量中 ,发现工程在 1998年 8月建成至10月间 ,坝田内形成了非常明显的淤积三角形 ,而在以后的观测中却没有再出现 .根据观测的资料 ,本文从潮流、地形、季节风以及淤积总趋势等方面对坝田内淤积三角形的形态特征、形成原因、发展变化及其对淤积效率的影响作了分析与研究 。

There appear a series of very distinct triangle area of deposit in net-shaped dams which is a project of the promoting deposit experimentation on Tiaozini sands, after two month the project was built in August 1998. However, this case didn't come in the latter time. Based on the information of observation in one year, this paper analyzed the configuration character, forming reason, evolution and the affect on depositing efficiency of the triangle area, from the factors of the tide flow, topography, monsoon and the general trend of deposit. This will help to design the best method to promoting deposit on Tiaozini sands.
