| 摘 要： | 用半解析元法分析了轴对称横观各向同性层合圆厚板与无限层土地基的静力相互作用，提出了一种新的半解析位移函数。采用在水平方向解析，在竖向进行离散化的方法，使静力相互作用的问题简化为一维数值计算问题，大大减少了计算工作量。数值计算表明：在工程上必须注意基础附近的表层土的弹性模量的确定，而H／R大于5～10的较深处的层土的特性可粗略估计；在结构和地基相互作用分析中，地基的计算厚度可取为地基深度H与基础的半径R之比H／R大于10。

| Abstract: | The interaction problem between laminated transversely isotropic circular plate and infinite layer foundation is analyzed by the semi-analytic element method. An analytic function are set used in the horizontal direction and the method of discreteness is used in vertical direction. Thus the interac- tion problem can be simplified to one dimensional numerical problem. The results form this study are as follows: we must consider the characteristic of every layer foundation which influence the statics displament of system; calculated thickness of infinite layer foundation is ten times as much as radius of laminated circular plate. |
