自升式抛石整平平台船的设计与应用

针对长江口深水航道治理工程恶劣的作业环境,将海上施工平台的概念引用到水下抛石整平施工工艺中,研究的主要内容包括设备的施工作业方式、平台的结构、平台自浮的拖航稳定性、平台支腿靴板对基础的压力、平台升降装置、抛石整平机构及作业时的稳定性等,阐述了平台船的特点和先进性,以及在今后大型水工工程中的应用前景。

Design and Application of Self-Elevating Rubble Leveling Barge

To counter the bad working condition of Yangtze River Estuary deepwater channel improvement project, this paper introduces the concept of construction platform at sea into leveling technology of riprapping underwater. The main contents of this research are ways of operation in construction, structure of platform, towing stability of platform' s self-floating, pressure of baseboard to floor, elevating equipment of platform, mechanism of nibble leveling, stability of working and self-depositing, ect. This paper expounds the characteristics and advanced features of leveling barge, and its application prospect in large-scale underwater engineering in future.
