铺排船应用于航道整治工程中，滑板最佳倾角的设定是铺排船设计过程中一项重要的指标，很多工程施工通过经验确定，以排体缓缓下滑作为锁定滑板倾角的依据,特殊情况下无法准确判断该状态。“半潜1”船舶进行铺排改造后，通过多次现场试验验证得出滑板与联锁片的摩擦系数范围为0.348～0.380；设定边界条件后，利用摩擦系数反算法及反求技术得出滑板最佳倾角为27.83°～30.38°，在该范围内可实现甲板布置2 m，滑板布置单排联锁片顺利溜放，对滚筒拉力达到最佳。

For the placing ship used in the waterway project, the setting of the best angle of the skateboard is an important index in the design process. A lot of construction is determined by the experience, but we can not judge the state under special conditions. After renovation of the“semi-submersible ship 1”, we get the friction coefficient range between the skateboard and interlocking pieces through many field tests, which is from 0.348 to 0.380. After setting the boundary conditions, we use the back calculation of friction coefficient and reverse engineering and obtain the skateboard best angle, i.e. 27.83°~30.38°. Within this range, we can achieve the deck disposition of 2 m, realize smooth humping of skateboards when arranged in a single row of interlocking sheet, and obtain the best drum tension.
