【摘要】 从土动力学的角度 ,本文认为按土的有效应力原理进行桩—土动力相互作用分析能够较好地反映土的动力特性对桩基的影响。又着重讨论了基于有效应力原理的有限元法 ,并对一个柱式桥墩桩基础进行了计算和分析。更多还原

【Abstract】 From the viewpoint of soil dynamics, this paper suggests that the effect of dynamic characters of soil on piled foundation can be expressed through analysis of pile-soil dynamic interaction. The FEM based on principles of effective stress was discussed and the calculation and analysis on piled foundation of column type bridge pier were carried out. [更多还原
