The Application Of Mathematics Simulation In Ocean Engineering Water Circumstance Influence Estimate

Since development quickly of our country economy, Circumstance matter of the engineering constructing owing to is attented increasingly to people. The day of people life quality is improved increasingly, the need is higher to people inhabitancy circumstance. Ocean is a carrier of modern economy developmented more, owing to fluidity and globality, is attented to people of all country. The circumstance matter is more importance owing to the engineering constructing. The bayou is a ligament connect in ocean and land, it is the most developed area and the most of people. Zhujiang Bayou lies it, it composes of the most complex rivernet system and bays. The channels are connectivity one another, the upriver water enters into the ocean via the eight bayous. The water and mass change distinctness by the current and tide, along with time and space. The mathematics simulation is a prodigious challenge to it because of complexity waterconfiguration and dynamical character, but since 80a 20^th , the study is begined.The character is 1- Dimension flow in rivernet, it is 1,2- Dimension flow in bayou, and is 2,3- Dimension flow. This paper studied the application of the 2-Dimension mathematics model in simulated the water circumstance of engineering, combined the mathematics simulation with locale investigation, validated the application of the 2- Dimension mathematics model in simulated the character of sea area tidal current and the locomotioned and diffused course of suspend bedload, integrate Guangzhou Xiaohu Petrifaction Dock Ocean Engineering Circumstance Influence Estimate.(1)It need investigate the character of sea area circumstance, the data taked on the continuity of time and space(include location); and obtained exactitude the numerical value simulated.(2)The 2- Dimension nonlinearity liquid mathematics model simulated tidal current of sea area, under a certain boundary condition, base on the character of tidal current, the law velocity is zero, considered glutinosity of water and the foece, adopted the non-configuration six-crunode triangle gridding, contrasted to locale investigated and validating, check ed up the reliability of simulated result, educed the coherence result.(3)The 2- Dimension liquid-diffuse mathematics model adopted analysed and accounted the locomotioned and diffused course of suspend bedload, it need area of engineering counted exactitude and quantity of maked suspend bedload, and it's character, integrated character of tidal current, simulated the area and time of suspend bedload effected, to the around water, and the possible circumstance problem, bring forward the solved method, controlled availably the ocean circumstance matter owing to the engineering constructing, played down least the ocean circumstance influence, and protected availably ocean circumstance.(4)This paper listed the question of the 2- Dimension mathematics model applied among the simulation the last, and expectation of the 2- Dimension mathematics model aftertime.
