The invention discloses a method for improving launching stability of a floating dock, which comprises the following steps of: providing a floating dock on which a loading object is loaded; calculating the steady center height KM value and the initial stability height GM0 value of the buoyancy body after the floating dock loaded with the load enters water; whether the initial stability height GM0 value meets the requirement or not is judged based on the minimum value GMminimum of the allowable initial stability height of the floating dock; when the judgment result is that the requirement is not met, calculating a difference value GM = GM0-GM minimum lt; and the value of the steady center height KM of the buoyancy body is increased to the minimum GM-GM0. According to the further scheme, a buoyancy tank is additionally arranged on the deck of the floating dock, the KM value is increased, the stability of the floating dock in the launching process can be effectively improved, and the problem that the floating dock cannot enter the water due to instability is solved.
本发明公开了一种浮船坞下水稳性改善方法,该浮船坞下水稳性改善方法包括提供一浮船坞,该浮船坞上装载有装载物。计算装载有装载物的浮船坞入水后的浮力体稳心高度KM及初稳性高度GM0值;基于浮船坞的许用初稳性高度的最小值GM最小,判断初稳性高度GM0值是否满足要求;当判断结果为不满足需求时,计算差值△GM=GM0‑GM最小<0,并增加浮力体稳心高度KM值至GM最小‑GM0。在本发明进一步地方案中通过在浮船坞的甲板上增加浮箱,提高KM值,能够有效提高浮船坞下水时的稳定性,避免由于失稳导致的无法下水的问题。
