摘　　要：考虑到裙桩套筒作为连接桩与导管架的主要构件,在导管架的设计计算中的重要性,而SACS对于局部构件的计算能力并不突出,探讨采用ABAQUS来计算校核裙桩套筒的具体方法,利用SACS进行整体计算,采用ABAQUS进行裙桩套筒的局部校核,结合软件的实际情况推导模型截断与恢复的具体步骤,以PY34-1项目为具体实例,进行裙桩套筒的校核。As the main component of the connecting pile and the jacket,the skirt pile sleeve is very important in the design and calculation of the jacket. Because the capability of SACS software is not outstanding for the calculation of local components,the method of assessing the skirt pile sleeve using ABAQUS was set forth. After he whole calculation in SACS,the local strength of the skirt pile sleeve was assessed by ABAQUS. The concrete steps of the model truncation and recovery were given. The PY34-1 project was used as a example to assess the skirt pile sleeve.
