ABAQUS桩基计算不收敛问题，求问？

warning信息如下：

Nodes 51314, 51310, 44833, 44865, 45417, 45418, 45577, 45651, 45652, and 51311 are part of a contact constraint, however all their degrees-of-freedom have been previously eliminated by other constraints. Abaqus will attempt solution and in case of failure will print appropriate messages regarding overconstraints.

Node 90 instance soil-1 is common between the contact pair (assembly_soil-1_zhuang2-zs-sizhou_cns_, assembly_soil-1_soil-zhuang2-zs-sizhou). No constraint is formed for this node.

诸如此类。。。。

我设置的桩和土体摩擦接触，桩底和土tie约束。尝试过点面接触和面面接触，均无法收敛。
