The Design And Optimization Of Tianjin Center Fishing Port Offshore Areas Vertical Cofferdam

In recent years, with the focus of China's economy is steadily moving north, the Bohai Rim region has gradually become an important area promoting China's economic growth. As the center of the Bohai Sea region, Binhai New Area is an important window and channel for China's"Opening-to the Outside World"strategy, so its strategic position is of great importance.Tianjin Center Fishing Port is located in the area between Da Shen Tang and Caijiapu in Hangu District, northeast part of Binhai New Area. The coastline of this area is reserved for the development of comprehensive utilization of Fishing and Sea-water, mainly develop large fishing ports, power plants, desalination and so on. The construction of Tianjin Center Fishing port is in line with Tianjin's shoreline-use planning , and this area will become the largest modern seafood distribution, processing centre of Tianjin as well as the whole Bohai Sea.Tianjin Center Fishing Port project is the major carrier for the development of Tianjin's new marine economy and the state-level key project for the promotion of the fishing areas urbanization. Vertical cofferdam Project is one of the initial project of the whole project, and also the basic project of this comprehensive large-scale project. Under the principle of reasonable design, cost saving, convenient construction, shorten the duration and by the comparison, the design program use reinforced concrete sheet pile.There are some datum differences in many ways between the theoretic calculation and actual engineering , especially in the soft-soiled hydraulic engineering , the comprehensive force index of earth and hydraulic pressures can be difficultly measured , and the calculation methods also have certain differences.In this thesis , the design data of the working area are briefed , the structure calculations are done with the Fenghai Port Calculation System in combination with the actual engineers.Through the theoretical calculation and actual monitoring analysis,the reliability and reasonability of the structure are used in the design are verified.After comparing the result of the theoretic calculation with that of the monitoring and construction , it is proved that all the presumptions and paramaters used in the design are right , which provides the basis for improving the design and raising the level of the whole engineering.
