挑流丁坝在海港工程中的应用
|
摘要
结合如东县小洋口(洋口镇)重装设备成套基地项目工程实例,对挑流丁坝在辐射沙州地区海港工程中,维护引堤、护岸围埝堤身稳定与安全进行了应用研究。结果表明,挑流丁坝的建设实现了促淤保滩,防止潮沟水平迁移,阻断潮沟落潮流对堤身的冲击与掏蚀,改变沿堤流的流向,使之与堤身保持一定的安全距离,对工程安全建设起到了重要作用。
Based on the heavy equipment installation complete basement project in Xiaoyangkou( Yangkou Town) of Rudong County, we conducted the application research of stability and safety of approach dike maintenance and cofferdam during the construction of the seaport in the radial sand ridge region. The results show that the construction of the spur dike has promoted the deposition and protected the beach, prevented the horizontal migration of tidal creeks, stopped the impact and erosion of current in the tidal creeks on the cofferdam, and changed the current direction along the cofferdam so that to maintain a certain distance with the cofferdam which has played an role of great importance in safely constructing the project.
