摘　　要：采用有限元通用分析软件,对自平衡加载方式下上、下桩段的相互作用及上下段桩位移影响量随桩土参数的变化情况进行了分析。结果表明,其影响程度很小,在测试结果的转换计算中可忽略。By means of the general finite element program, this paper analyzes the interactions between the upper and lower pile sections tested with self-balance loading method, and the influential amount of the displacement of the two sections of the pile with variation of pile soil parameters. The analyses indicate that the influences are slight, and can be neglected in the conversion calculation of the test results.
