In this paper, a general, strain-consistent, third-order displacement field of shells is proposed. On this basis, the nonlinear theory of composite laminated shells including third-order transverse shear deformation and rotary inertia is developed. Hamilton's variational principle is used to derive the nonlinear static and dynamic governing differential equations and the corresponding boundary conditions of composite laminated anisotropic general shells under the orthogonal curvilinear coordinates. And the form of spherical shells is degenerated.

The influence of the structure and material parameters on static and dynamic characteristics is studied. The three dimensional static analysis is obtained by the power series expansion method for a piezoelectric composite laminates. Three dimensional distribution of bonding stress, displacement and electric potential are presented. The distributions of electric potential across thickness of two kinds piezoelectric materials are discussed.

The result shows that, under the condition of the same thickness of material, increasing the number of layers properly can weaken the press, the cutting damage and the destruction due to extension, and lower the impact energy on the construction effectively. In particular, multi-layered protection construction is rather striking in its advantage of destruction-resistance under high stress and low impulse load.

结果表明，分层总厚度相等的条件下，适当增加分层数目可以有效减小冲击载荷对结构的压、剪损伤和拉伸破坏，降低结构所受的冲击能量，尤其对于高强度、持续时间短的脉冲载荷，多分层防护结构的抗毁伤能力优势更为明显。

The minor principal stress of slab, the maximum acceleration in up-down stream direction and permanent deformation of the dam body for three-directional earthquake excitation are obviously different from those for unidirectional and two-directional earthquake loading.

计算表明，多向地震动下的面板峰值小主应力、顺河向峰值加速度及坝体的永久变形均与单向和双向输入时显著不同，实际工程计算时应同时考虑三个方向的地震动；振动型地震激励引起的坝体反应明显大于冲击型地震激励；随着地震动强度的增加，峰值加速度、峰值剪应变、面板应力和周边缝变形等增加；面板刚度对面板的应力值和周边缝的变位具有较大影响，当面板模量取值较低时，计算所得到的"面板"应力集中部位不甚明显，计算结论为新型的"土工膜面板堆石坝"提供了理论依据。
