摘　　要：目前,锚系施工船舶主要使用传统抓力锚作为定位锚在海上施工,只有足够的拖拽距离,才能提供满足要求的抓力,所以并不适合在拖拽距离受限的海域使用。重力锚自身重量较大,对安装区域的海床承载力有一定要求,在安装重力锚前,需要校核安装区域的海床承载力。重力锚在海床上的沉降深度可以直接反映海床承载力,介绍一种重力锚在海床中沉降深度的计算方法,可以简便地计算出重力锚的沉降深度。At present,the traditional fluke anchor is mainly used as the positioning anchor for offshore construction vessel.The traditional fluke anchor needs to have enough dragging distance to provide the required force.Therefore,the conventional fluke anchor is not suitable for use in the sea area with limited dragging distance.Due to the large weight of gravity anchor itself,there are certain requirements on the seabed bearing capacity of the installation area.Before the installation of gravity anchor,it is necessary to check the seabed bearing capacity of the installation area.The settlement depth of gravity anchor on the seabed can directly reflect the seabed bearing capacity.This paper introduces a method for calculating the settling depth of gravity anchor on seabed,which can be easily calculated.
