| 摘 要： | 利用弹性矩形板与多层地基表面的竖向位移协调条件与光滑接触条件,由横观各向同性多层地基应力与位移非耦合的传递矩阵解,推导出弹性矩形板下竖向应力和位移的解析解。在此基础上,编制了相应的程序,并进行了数值计算。计算结果表明:矩形板刚度对板底竖向位移及板中心下的竖向应力有着较为显著的影响;板底竖向位移及板中心下的竖向应力随着板刚度的增加而减小,相同荷载作用下横观各向同性地基与均匀各向同性地基模型的计算结果差异较大,实际工程中很有必要采用更符合土体性质的横观各向同性地基模型。

| Abstract: | Based on the continuity of vertical displacements and the smooth contact conditions between the transversely isotropic layered soils and the elastic rectangular plate,the analytical solution of transversely isotropic soils under the elastic rectangular plate can be obtained by using the uncoupled transfer matrix solutions for displacements and stresses of transversely isotropic layered soils.Numerical calculation and analysis are carried out by the computer program.The numerical results show that the rigidi... |
