摘要
提出大口径桩动测存在的三维效应现象.通过合理的假设,建立了大口径桩的三维动测模型.较详细地介绍了其动态平衡方程的建立过程,同时对动态平衡方程的解法也作了一般的介绍.通过模拟可对不同几何形状和缺陷的桩设计不同的参数进行正演推算.
This paper presented threedimensional effect in pile with large dimension testing, established the dynamical testing model by rational assuming. Detailed recommend the established process that dynamical equation is established, at the same time, make generally introduced at solution the dynamical equation. It can forward modeling difference sample pile.
