摘要 本文将下水墩木、滑板、滑道及地基等理想化为一个串联弹性系统,应用弹性基础梁理论推导和建立了船底与下水墩木之间压力纵向分布的计算方法。该方法考虑了下水滑道地基不均匀下沉的影响因素。并以一艘实船为例进行了计算,结果表明本文所给出的计算方法是可行和有效的。 In this paper, the launching wooden blocks, sliding way, standing way and foundation are regarded as an ideal serial elastic system. Based on the theory of elastic beam foundation, a new practical method for calculating longitudinal pressure distribution between bottom plate and launching wooden blocks is presented, in which the effects of non-homogeneous sinking of slipway is considered. It is illustrated by numerical example of a lanuching vessel that the proposed method is reasonable and feasible.
