摘要/Abstract

摘要： 介绍了几种国际上广泛应用于深水锚泊的新型系泊基础（吸力锚、法向承力锚、吸力式贯入锚和动力贯入锚），并结合国内外的最新研究进展，分别针对吸力锚安装过程中的海床阻力和内部土塞发展、服役阶段的承载力特性，法向承力锚安装时的拖曳轨迹和三维受力状态下的承载力，吸力式贯入锚的“keying”过程，动力贯入锚的最终安装深度和承载力，以及锚泊线与海床的接触问题等当前国际上研究的重点和热点内容进行了简要地评述，旨在通过分析当前新型深水锚在设计、施工以及承载机制等方面的不足，以探索深水系泊基础发展的新趋势

关键词: 吸力锚, 法向承力锚, 吸力式贯入锚, 动力贯入锚, 锚泊线

Abstract: Several new types of deepwater anchors widely used in the world, including suction anchor, vertically loaded anchor, suction embedded plate anchor and dynamically penetrating anchor, are detailedly illustrated. Based on the overview of recent works at home and abroad, some key and hot problems are presented and discussed briefly, which are the seabed resistance and soil heave development during the suction penetration process of suction anchor, the anchor capacity in service, the drag trajectory of vertically loaded anchor and its capacity under a three-dimensional loading state, keying process of suction embedded plate anchor, installation depth of dynamically penetrating anchor and its pullout capacity. Hence, the deficiencies in current design, field installation and bearing mechanism can be recognized, aiming to explore the new developing trend of deep-sea anchoring foundations.

Key words: suction anchor, vertically loaded anchor, suction embedded plate anchor, dynamically penetrating anchor, mooring line
