摘    要：根据半无限正文各向异性板在其边界上受法向集中力时板内应力分量的表达式,推出了横观各向同性析内及边界上的位移分量计算式,并用于横观各向同性地基上基础梁的内力计算.讨论了链杆法及级数法,推导证明：可将计算各向同性地基上基础梁的链杆法及级数法的表格移用于此,只需将与地基和基础梁力学性质有关的组合系数(已推出)作一代换.计算了例题,说明地基垂直与水平向变形模量不同对基础梁内力有相当影响,设计时必须考虑.

Abstract: This article has induced the expressions of the displacement components in a half infinitetransverse isotropic board which is loaded by normal concentrated force at its edge and theexpression of the settlement at its surface. This result has been applied to calculate the fun-dation beam on this sort of ground.The method of connecting rod and power series has beenused.It is shown that the tables of calculating the fundation beam on isotropic ground by the two methods can be used here. The examples have been computed.Calculation shows thatthe difference between the modulus of deformation in vertical and horizontal directions has certain influence on the beam, and it is necessary to consider it.
