| 摘 要： | 建立了结构气浮静稳性分析的理论方法。导出了非对称多体气浮结构的初稳性高度的计算式。理论计算得到的稳心半径与模型试验和现场原型试验的测算值非常吻合 ;通过稳性高参数与静稳性曲线切线斜率的比较 ,气浮结构的静稳性分析理论和浮态分析理论得到了相互验证。所建立的气浮结构静稳性分析理论和浮态分析理论符合实际情况 ,可以在工程中应用 ;由于气浮力折减系数的影响 ,气浮体的浮稳性比对应的实浮体的浮稳性差

| Abstract: | A theoretical method is developed to analyze the static stability of air floated bucket foundation structures with small rolling angles. A formula is presented to calculate the meta centric height for unsymmetrical air floated structures with multiple floating bodies. The theoretical meta centric radius coincides well with the results of model and prototype tests. The static stability analysis theory and the state analysis theory predict the same meta centric height and tangent slope of the stabilizing force arm curve. The results show that the static stability analysis theory can be applied to engineering problems. Calculations show that the air floated structure is less stable than the conventional floating structure because of the decreased influence of the air buoyancy. |
