The Research On Hydrodynamic Characteristic Analysis Of Ship Lock And Navigation Tube System

Many locks and dams at hydroelectrical stations on potamic navigations have became choke point of ship development in our country at present.With economic development and the going-up demand for ship in freshwater,the way through locks both using making navigation tunnel and setting up ship lock is one feasible project in resolving the problem of navigation at bar:locks and dams.The project is brought forward for the first time at the engineering feasibility research on changing the ship choke point at Qililong,Fuchunjiang in Our procince.But ship lock irrigatting and ventting water brings stream and concussive wave,which influence ships' navigation in the tunnel at joint with leading sea-route upriver,so how to lay water-carriage system as well as research on hydrodynamic parameter,hydrodynamic character in tunnel and examination work are very pivotal.This can provide scientific gist for idiographic design project.Basing on the example of the second routeway engineering at Qiligang,Fuchunjiang.this paper does some research aboat hydrodynamic character when ship lock and navigation tunnel are connected.The main content and innovating point in this paper are as below:1.Basing on laying water-carriage system of ship lock,mathod of openning water-carriage valve as well as analysis on water-carriage time,reasonable mathematics model is set up.Then compute and analyze hydrodynamic character in transporting water through ship lock,the condition of unsteady flow and hydrodynamic eigenvalue,such as section velocity of flow,water level,surface waving along the way and so on.Abecedarianly estimate the flow conditions in the navigation tunnel when ship lock irrigating water.2.The value of computing hydrodynamic character of navigation tunnel are inosculated with examination,which makes clear that mathematics model and mathod used for hydrodynamic compuing are in reasonable.Also,basing on the hydrodynamic eigenvalue demand of navigating safely in the tube,some suggestions are brought up in designing projece.3.The settinging way between Ship lock leading sail-route and navigation tunnel of being connectted dirrectly is not have one example oversea.The computting and analysis on hydrodynamic character in the tunnel when water-carriage have practical engineering value,and at the same time it takes the part in leading an important way to resolve out the problem from bar:locks and dams.
