摘要
分析了群桩沉降验算中接触单元具体应用的一些问题，包括单元剖分中接触单元的选取与设置范围，对刚性桩和柔性桩接触单元的应用作了分析比较，并建议了接触单元的弹塑性模型．
Some problems in the application of contact element are analyzed in settlement checking of the group pile,including the Selection and arrangement scale of contact element. Soggestion is proposed with comparison of applicationbetween rigid piles and flexible piles. An elastic-plastic model is built for contact element.
