| 摘 要： | 结合某半潜船空载静水力数据和液舱的相关数据提出一种半潜船质心高度计算方法,然后根据半潜船的稳性变化曲线得到其稳性随吃水变化的控制点,通过对比半潜船的质心高度与极限质心高度来确定其装载大型沉箱及异形型沉箱的施工可行性,可进一步形成具有查询、计算功能的数据库为施工人员决策提供参考。

| Abstract: | A method is presented for calculating the gravity center of semi-submerged ship based on the hydrostatic data and tank data.The control points of stability changed over ship draft is obtained from stability curve.Then,the construction feasibility of loading the large caisson and special shaped caisson is determined by comparing the height and extreme height of the gravity center of semi-submerged ship,and a database with query function and calculation function is formed,which can be used to provide references for construction. |

| Keywords: | semi-submerged ship caisson loading capacity extreme height of center of gravity center stability |
