摘　　要：对于埋设在海底泥面下的锚锭系统,其抗拉能力是随着回填土强度的提高而逐渐提高的,为了船舶系缆的安全性,有必要确定基坑回填后锚锭系统的抗拉能力增长情况。采用ABAQUS有限元软件研究两者之间定量关系的计算方法,结合工程实例进行计算分析。采用温控参数折减法和"三步走"的计算思路,可以得出两者之间的公式关系,结合回填土和原状土的实际强度,可以计算某一时期锚锭系统的抗拉能力值。The tensile strength of an anchor system buried under the surface of the seabed mud increases gradually with the increase of backfill strength.In order to guarantee the safety of ship＇s mooring,it is necessary to determine the tensile capacity growth of anchor system in the pit backfill.Using the calculating method of ABAQUS finite element software,we study the quantitative relationships between them combining with engineering examples.Adopting the temperature-controlling parameters＇ reduction method and ＂three-step calculation＂ thinking,we obtain the formulae for the relationship between the two.With the actual strength of the backfill and undisturbed soil,we can calculate the tensile strength of the anchor system in a given period.
