| 摘 要： | 通过实验发现岩土地基中普遍存在各向异性现象 ,而目前按照各向同性地基模型计算势必会引起较大误差 ,为了提高地基中应力和沉降计算的精确度 ,本文将各向同性轴对称问题下的拉甫位移函数推广到横观各向同性地基轴对称问题 ,得到了位移分量与横观各向同性下拉甫位移函数的关系式 ,并通过积分变换得到了横观各向同性地基应力和沉降的通解

| Abstract: | It′s shown by experiment that the rock*.soil foundation is anisotropic.Therefore,more errors will be made if calculating is based on the isotropic foundation model.In order to improve the precise of stress and settlement in foundation,the Love displacement function on the axisymmetric problem of isotropic elastic half*.space has been extended to the axisymmetric problem of transversely isotropic foundation.The expressions of displacement stress and the Love displacement function have been obtained.By means of integral transformation,the general solution of transversely isotropic foundation is available. |
