考虑侧阻力软化的单桩竖向荷载传递方式分析--基于位移协调法

Based on the differential equation of vertical load transfer of single pile, and considering softening of side resistance force, the expression in increment form was deduced which concerned relation between axial force of pile and displacement of pile relative to soil of pile side. Then according to the expression and method for harmony of displacement, relation curve between load and settlement was figured out. The result was proved to be appropriate by compared the computing result with the test one, and could explain progressive failure of pile bearing vertical load. So this new method can be used to guide practice of engineering.
