摘要
提出四节点映射无限元，用此类单元与有限元及双向映射无限元耦合模拟直立式沉箱地基基础。数值计算表明这一耦合系统与有限元地基模型相比较，提高了位移、应力计算精度，结果还表明地基与沉箱箱体的相互作用对箱踵。
This paper presents 4 nodes mapping infinite elements The far field foundation of the caisson is simulated by such elements The results shows the model has a high accuracy in comparison with the finite element model In addition , the significant effects on stress distribution at the heel and the toe of the caisson proved that the consideration of caisson and foundation interaction is of importance to the analysis
