| 10. | In the study of the lumber carrier , one of the very important problem is the in spot and ultimate station due to flooding which will bring tremendous threat to the ship because of the few holds in order to study the lumber carrier buoyancy , stability and longitudinal strength under the condition of flooding , the paper adopt fundamental ship principle and iterative and accumulative concept on the basis of insumersibility theory to detailedly calculate the flooding speed flooding amount front draft after draft stability and longitudinal strength considering the ship " s sinking and inclination which will change the center of gravity and the loading station both in hold and on deck and the effect of flooding and lumber amount in holdo in the last , the paper introduces an example of the actual ship named " fei yun ling " and makes a contrast between not taking measure and taking measure which draws a reasonable conclusion and comes up to some advice the method avoids the cockamamie calculating while insures enough precision the paper draws a conclusion that not all the lumber carrier will submerge when suffering the damaged flooding if the loading or measure is suitable
为了研究运木船舶在破舱状态下的浮性、稳性和强度，本文在抗沉性理论的基础上，运用船舶基本原理，采用了迭代和累计的思想，将船舶的进水过程划分为很多次进水的积累，详细计算了运木船在破舱进水的过程中，考虑到各种破舱参数、船舶本身的下沉、舱室内木材、甲板货的装载情况和在进水过程中船舶本身的倾斜对进水重心的影响，以及舱室内的进水量和木材对破口处进水速度的影响，船舶总的进水速度、进水量、首尾吃水、稳性的实时状态和最终船舶的总纵强度，给出了计算实例，并进行了在采取用泵抽水前后浮态参数的对比，得出了该船舶在舱室内的货物积载量达到某个数值时可以保证船舶在破舱进水时不会沉没，或者在当开口小于某数值时，采取适当的措施后，可以使船舶避免沉没。 |
