Research Of One-dimension And Two-dimension Hydraulic Calculation On Sea Reclamation

Closure is the key of success on Sea-closure Engineering. Technical matters are the most complicated and difficult puzzles on Sea-closure Engineering, which come from construction work on crevasse. Considering practical situation on crevasse, the program RMA2, which comes from mathematic model program SMS on two-dimension hydrodynamics, has been used to simulate hydrodynamic situation on crevasse. Then scientific gist will be supplied for the closure of crevasse.Literature analysis has been done at the beginning of this dissertation, which mainly are the current development and exploration of domestic and international Sea-closure Engineering, and introduce the characteristics of Sea-closure Engineering as well as the experience, lesson and which matter should be settled in the future. This paper mainly introduces one and two dimension computational theory and methods of the Sea-closure, and direct toward the Sea-closure engineering of the eleventh seawall in Jiaojiang, Zhejiang province, which is the strong tide estuary in Taizhou gulf. On the same condition of Sea-closure project, this dissertation carry through one and two dimension hydraulic calculation of Sea-closure, and through comparing with those two hydraulic calculation results, this paper puts through some valuable conclusion to the Sea-closure Engineering.The author advises that to the hydraulic calculation on large and medium-sized Sea-closure Engineering, we should sum up the strongpoint of one-dimension and two-dimension hydraulic calculation, and then can more precisely master the velocity characteristics of crevasse, thus can design safe and stable cut-off dike.
