地基与上部结构相互作用的边界元理论分析

BEM Theory Analysis of Interaction Between Foundation and Superstructure

利用边界元法对地基与上部结构相互作用做了较为具体的理论分析。与以往传统有限元法相比 ,边界元法显示了在数值分析中的几个优点 ,特别是在无限区域或半无限域情况下 ,比运用有限元法进行分析 ,具有更大的优越性。因此在特定情况下 。

Interaction between foundation and superstructure has been analysised concretely with BEM theory.Been compared with conventional LEM,BEM shows several merits in numerical analysis.Especially,there is much more superior in analysising infinite field or semi infinite field with BEM than with LEM.As a result,there should be very valuable to substitute BEM for LEM in numerical analysis under certain circumstances.
