The invention discloses a ship docking block bearing reaction calculation method, which comprises the following steps of: drawing a docking block arrangement drawing according to the actual docking block arrangement condition of a shipyard; then calculating the bearing reaction of each characteristic block placing point in the stern fin area, the middle area and the stem area of the ship in different drafts so as to obtain the total bearing reaction of all docking blocks and the bearing reaction of the stern docking block; if the average bearing reaction of a single docking block at the sternpart is greater than the maximum bearing reaction force allowed to be used by each docking block under the condition of different drafts, adjusting the number of the stern docking blocks and the docking block distance, recalculating the bearing reaction until the average bearing reaction of the single docking block at the stern is 0, and drawing a curve of the total bearing reaction change condition of all the docking blocks and a curve of the bearing reaction force change condition of the single row of docking blocks at the stern in the whole dock floating process of the ship. According to the method, the calculated bearing reaction is closer to the reality than the bearing reaction calculated by directly utilizing the characteristics of the ideal rigid beam in the traditional method by utilizing the flexibility of the actual ship body, and the result is more real.

    一种船舶坞墩支反力的计算方法,根据船厂实际的坞墩布置情况,画出坞墩的布墩图;之后计算出船舶在不同吃水时艉鳍区、中部区和艏部区中每个特征搁墩点的支反力,从而得到所有坞墩的总支反力及最艉部坞墩的支反力;如果在吃水不同的情况下出现最艉部单个坞墩的平均支反力大于每个坞墩允许使用的最大支反力时,则调整最艉部坞墩的数量和坞墩距离,重新计算支反力,直至当最艉部单个坞墩的平均支反力为0时,则绘制出船舶在坞内起浮全过程中所有坞墩的总支反力变化情况的曲线以及最艉部单排坞墩的支反力变化情况的曲线。该方法中利用实际船体的柔性使计算出的支反力比传统方法中直接利用理想刚性梁特性计算出的支反力更加接近实际,该结果更加真实。
