Research on protecting range of main navigation span of Donghai Bridge

摘要

The first phase of the Yangshan Deep Water Port Project consists of four sections: port area, Donghai Bridge, Hu-Lu Expressway, Lu Chao Port on-land component part. The construction of Donghai Bridge can meet the requirements of the Yangshan Port Area on container collection and transportation. It also ease water supply, power supply and communication, etc. After accomplishment, it appeared a lot of piers, which caused restrictions of navigation, difficulties of shipping, accidents of collision and damages to both person and ship. Therefore, a research on four navigation channels is necessary. This article is a study on protecting ranges and measures of main navigation span through drift route, area affected, rinse time and crash rate got from the result of ship's modeling and simulation experiment.
