Based on the difference between the corresponding limit of displacement from both side of contacted bodies, a local direct error estimator of BEM solution for 3D elastic contact problem is presented, and then a scheme of adaptive BEM is suggested.

• 在此基础上提出将接触体接触单元间与域内解连续的边界位移之差的某种度量作为三维弹性体接触问题边界元法的一种误差直接估计，并且提出了三维弹性体接触问题边界元法的一种自适应计算方案。
