虚功率原理求解各向异性和非均质地基的极限荷载

Solution to the Limit Load of Anisotropy and Nonhomogeneous Foundation by Means of Virtual Work Principle

针对虚位移原理的局限性 ,提出了适用于各向异性非均质地基的虚功率原理的新概念 。

To make up for the limitation of the principle of virtual displacement, the virtual work principle is advanced which can better apply to anisotropy and nonhomogeneous foundation. A basic formula for the limit load of foundation is derived from the combination of the virtual work principle and the variation principle.
