【摘要】 对复杂地基采用四面体单元,而上部结构采用六面体单元的地基与结构相互作用问题,建立了交界面上位移协调的非一致网格解法,同时将薄层单元作为结构或地基的附属单元可以求解地基与上部结构之间在非一致网格条件下的摩擦接触问题。算例表明本文的方法是合理、有效的。更多还原

【Abstract】 when the foundation’s conditions are complex and the foundation-structure interaction is considered, the tetrahedral element is applied in the foundation and the hexahedral- element is applied in the structure. Compatible displacement method of different mesh is applied on the interface of foundation and structure. Furthermore, contact element as attached to structure or foundation is applied to the field of contact in this case. An example proves the correction and the efficiency of this method in the paper.更多还原
