The submergible control platform width was positively related with the diameter of cage framework. The relation was k=1-2+22r-h_4~2+14l~2+12r~2-22rl, in formula h_4 was the platform height, which was restricted by the water depth. There h=h_1+h_2+h_3+2h_4+12H, in equation h_1 stood for net sheepshank height, h_2, the height of gravity setting on the bottom net, h_3, the distance from gravity setting to submarine, H was estimated maximal wave height while typhoon occurred in cage areas.

控制平台的宽度l与网箱主构架半径r正相关，设计时必须满足网箱框架外侧与平台的距离k大于零，其中：k=1-2+22r-h42+14l2+12r2-22rl，h4为控制平台高度，其受放置区水深h的制约，高度与水深的关系：h=h1+h2+h3+2h4+12H，h1为网衣缩结高度，h2为网衣底部重力装置高度，h3为重力装置到水底的距离，H为网箱放置区台风期预计最大波高。

In this thesis, I summarize the theoretical calculation method, applied scope and notice of siphonic drainage system, and point out the advantage of siphonic drainage system compared with gravitation drainage system. In the archetype experiment study of siphonic drainage tube, I adopt different tube diameter and different structural height to survey the drainage volume and press in different place. I observe various kinds of flow state, and get chief factors which influence hydraulic peculiarity of system as the tube diameter or structural height, and find out the relevance of factor to flux. I apply CFD Fluent software and adopt standard k-ε model and RNG k-ε model, then use finite volume method and second-order upwind scheme to discrete numerical model, while coupling numeration of velocity field and press is based on SIMPLE. In the numerical simulation of curved part of tube, siphonic drainage tube experiment system and multi-outlet siphonic drainage system, I make research on internal velocity and press of system in different project condition by changing the tube diameter of curved part, negative press value in tube export and improving the quantity of water gutter.
