摘要
针对霍尔锚在静水中的垂直落锚情况,通过理论分析和物理试验,分析锚质量、触地速度、海床土体强度,以及土体粒径等对霍尔锚贯入力峰值及相应贯入深度的影响.结果表明,贯入力峰值及其对应的贯入深度与锚质量和触地速度呈二次函数关系,与土体粒径呈指数函数关系,以此分别提出霍尔锚贯入力峰值及相应贯入深度的计算公式,为海底结构物强度的设计与防护提供技术支撑.
Abstract
According to the vertical dropping of Hall anchor in still water,the influence of anchor mass,contact velocity,seabed soil strength and soil particle size on the peak penetration force and corresponding penetration depth were investigated through theoretical analysis and physical test.The results showed that the peak penetration force and corresponding penetration depth have a quadratic function relationship with the anchor mass and ground contact velocity,and an exponential function rela-tionship with the seabed soil particle size.The formulas to calculate the peak penetration force and corresponding penetration depth of the Hall anchor were proposed,which can provide technical support to the design and protection of underwater struc-tures.
