【摘要】 吸力式沉箱基础是一种用于海上浮式结构的新型基础型式,因其具有运输与施工方便、节省工期、可重复使用及造价低等优点,所以在海洋工程中得到了较为广泛的应用,其承载性状也是目前的研究热点之一。关于吸力式沉箱基础,至今尚未有一个得到广泛认可的抗拔破坏标准,也没有专门针对其破坏标准的研究报道,因此探讨吸力式沉箱基础的抗拔破坏标准对其承载性状研究有重大意义。结合荷载作用点位置和荷载作用方向两个因素对目前国内外已有的吸力式沉箱基础抗拔破坏标准进行了综述分析,并指出了现有吸力式沉箱基础抗拔破坏标准存在的问题和研究发展的方向。更多还原

【Abstract】 Suction caisson foundation,a new foundation type used for offshore floating structure,is more widely used in marine engineering and its bearing behavior is also one of the current research focus due to a variety of advantages,such as convenient transportation and construction,saving time,reusability and low cost.So far,there are no widely recognized uplift failure criterions and studies specifically about the uplift failure criterions of suction caisson foundation.Therefore,it is very necessary to discuss the uplift failure criterions of suction caisson foundation.The existing uplift failure criterions are reviewed and analyzed based on load point location and loading direction.Finally,the existing problems and research direction of the uplift failure criterion of suction caisson foundation are pointed out as well.更多还原
