根据横观各向同性单层地基的解析层元,结合土体之间的层间连续性条件,得到了横观各向同性层状土体在任意均布荷载下的位移解答。结合弹性矩形板与层状地基表面的位移协调条件和光滑接触条件,推导出横观各向同性地基与弹性矩形板共同作用的解析解。随后编制了相应的Fortran程序进行数值计算,分析了板土刚度比、土体横观各向同性和土体层状特性,模型中各个参数对计算结果的影响。结果表明:板土刚度比?、横观各向同性参数m和层状性质参数?对计算结果影响更大,横观各向同性参数n和层状性质参数β影响则相对较小。
According to the analytic layer element of the transversely isotropic monolayer foundation and the inter-story continuity condition of the soil, the displacement solution of the transversely isotropic layered soils under arbitrary uniform load is obtained. According to the displacement coordination condition and the smooth contact condition between the elastic rectangular plate and the layered soil, the analytic solution of the interaction between the transversely isotropic subgrade and the elastic rectangular plate is deduced. Subsequently, the corresponding Fortran program was developed to calculate the stiffness ratio of soils, the transverse isotropy of soils and the characteristics of layered soils. The influence of various parameters in the model on the calculation results was analyzed. The results show that the stiffness ratio of soil to plate, the transverse isotropic parameter m and the laminar property parameter have greater influence on the calculation results, and the influence of transverse isotropic parameter n and laminar property parameter β is relatively small.
