海峡火车渡轮的“坐底式”方案探讨

A Concept of the "Sit Bottom" Rail way Ferry on Channel

海峡火车渡轮在靠岸时实行岸轮轨道对接的主要困难是渡轮的运动和潮差使岸轮间相对高度差发生变化。“坐底式”方案是使渡轮坐底在停泊处的海底平面上,处于稳定的静止状态,岸轮间相对高度差也成为定值的方法。适当的选择坐底平面高度和渡轮甲板型深及其它参数,可使此定值为零,从而实现岸轮轨道平稳连接。 本文阐述了方案的可行性和有关参数计算,并对涉及的主要问题进行了探讨。

The raiway ferry movement and the height difference between high tide and low tide are two main troubles for track - linking between the ferry and wharf at wl'ich the ferry berth. 'Sit bottom'plan in which ferry sit down the sea bottom by wharf in stable condition with the fixed height difference between wharf and ferry deck is presented. Adequate selection on the factors of sit - bottom plane height and the ferry deck depth etc. is able to make' the difference equal zero so that link the tracks in stable condition. The plan feasibility and factors calculation is described and the major problem is discussed.
