大型抓斗船在开放海域浅水航道的施工

Construction of Large Grab Vessels in Shallow Water Channels in Open Seas

抓斗船在港口航道建设中发挥重要的作用,但受制于航道通航要求,风浪,水流以及自身的机械灵活性的限制,主要用于港池,泊位以及其他施工船舶难以开挖的边角,坚硬土质的施工。本文结合苏里南浅水航道的开挖,针对在浅水,通航航道,风浪大的工况条件下施工分析与总结,对今后遇到类似的工况条件具有一定的借鉴意义。

The grab ship plays an important role in the construction of the port channel,but it is limited by the navigation requirements of the channel,wind and waves,water flow and its own mechanical flexibility.Corner,hard soil construction.Combined with the excavation of the shallow water channel in Suriname,this paper analyzes and summarizes the construction under the working conditions of shallow water,navigable channel and strong wind and waves,which has certain reference significance for similar working conditions in the future.
