| 摘 要： | 通过引入虚设应变的概念，导出了具有原始缺陷的连续体的非线性应变几何关系，在此基础上引入薄壳理论的基本假定，导出了有初始几何缺陷的压力容器结构的非线性应变位移关系，为有初始几何缺陷的容器结构的非线性问题的研究提供了理论基础。

| Abstract: | The nonlinear strain and displacement relationship of continuum with original geometricjmperfections are deduced with the aid of introducing the concept of imaginary strains. On this basisthe basic assumptions of this shells theory are used to derive nonlinear strain components of shell vessels with the initial Seometric imperfections, and therefore the theoretical hots for the study of nonlinear geometric problems of vessels with initial geometric imperfections is provided. |
