在总结前人对壳斗科叶结构和叶表皮研究和本研究结果基础上列出了属的检索表和70种的检索表。

Based on Three Gorges Project, the following aspects about the three typical embedding manners are studied:(1) The border condition of cyclic symmetry is applied to the finite element models with contact among cushion layer, penstock and concrete. The effects of elastic modulus, thickness and placement extent of cushion layer on the stress of its around concrete are analyzed. It is suggested that the ratio of thickness to elastic modulus can be used as an important parameter in the design of cushion layer.

因此，本文结合三峡工程建设实践，在收集和总结前人经验的基础上，以大型通用有限元分析软件ANSYS为平台，对不同埋设方式的巨型蜗壳结构进行以下几个方面的研究：(1)引入循环对称边界条件，考虑垫层-钢板-混凝土之间的接触摩擦，建立有限元模型；并对垫层敷设范围、垫层厚度和弹性模量等设计关键参数进行了优化，并把"垫层弹性模量与垫层厚度之比"作为参考指标进行设计。

Based upon the energy-dissipation mechanism, the mechanical model of the damping layer sandwiched by plates or cylindrical shells is set up with the deformation energy method and the theory of modal analysis.
