摘　　要：推木船是库区或坝区推送木材过坝的专用水上设备，双体推木船是目前国内外尚无的一种新型推木设备．根据推木船推木机理，对速度的相似换算、船与木材的阻力换算、推木架受力计算等理论进行了研究．对推木量、船型、推进机构、推木架结构及形式、推木速度、对木材的切割能力及方式、与水力加速区的配合以及拖带能力进行了全面的试验研究，并进行了实船设计．采用了转动导流管推进操纵装置，全液压推木架操纵机构等技术．该船在非推木季节可兼作旅游客船使用，对舱室布置、装璜造型作了适当处理，使该船能拖、能推及旅游，达到一船三用．A log push ship is a special marine equipment to transport log over a dam in a reservoir zone. The log push catamaran is a new log push equipment. There is not another one at home and abroad. According to log push mechanism, the velocity analogical calculation, the ship and log hydraulic resistance calculation and the log push arm strain calculation are investigated. The quantity of log being pushed, the ship type, the propelling machinery, the structure and type of log push arm, the log push speed, the ability and method of log taking, the match with hydraulic accelaration zone and the ability of towing are tested and analysed throughout. The real ship are designed. There are rotated duct propelling and steering equipment and hydraulic log push arm driving system in the ship. The ship can be used as tourist ship and passenger ship in seasons without work. There are some special arrangement in the cabin and decoration for this purpose.
