为了能在实际工程中更好地运用这类结构，本文提出一种空间异形柱框架结构的非线性有限元分析方法，并结合单向及反复推覆分析方法对空间异形柱框架结构抗震性能进行分析，然后在推覆分析的基础上做一定的动力时程计算，另外还做了一些试

This is generally defined as being identical in the length to the width of the footing in the direction normal to the analytical plane. However, there is little knowledge about whether the results obtained from the historic method analysis are overestimated or underestimated, comparing with those obtained from the applicable values. So in this paper a new methodology considering the soil-pile dynamic interaction for sea warf has been imposed.

在总结理论的基础上，指出土-结构动力相互作用目前的发展水平与工程实用之间仍存在相当大的差距，理论与实际之间也还有距离，这是由于土-结构动力相互作用问题本身的复杂性，不同的计算方法都引进了一些假设和进行了不同程度的简化，以致不同方法给出的结构和地基反应存在有很大的差别，加之计算工作量大，试验验证也比较困难，所以在实际的抗震设计中考虑桩-土共同作用是有很大的研究意义的。

Nowadays, this structure is widely used although its design theory can not keep up with its engineering application. With the development of the west regions,with the construction of more infrastructures e.g. railways、highways and water conservancies, this kind of retaining wall will be more popular. So this paper does a research on this retaining wall based at a practical site.

目前这种结构应用较为广泛，但是其设计理论相对滞后于工程应用，随着国家西部大开发战略的实施，更多的铁路、公路和水电等基础设施项目陆续投入建设，桩基托梁挡土墙支挡结构也将大量应用，所以本文结合实际工点对桩基托梁挡土墙结构进行了研究。

Compared with general structures, since for beams and cylindrical shells, the geometrical equations are mostly simplified in forms, so their bucklings are playing an important role in the structural stability, which have increased great developments in the theories of structural stability.

圆柱壳是工程中最常使用的结构形式，从某种意义上来说，对这类结构屈曲问题的研究，推动了结构稳定性理论的发展。

All kinds of engineering structures are susceptible to structural damage during their lives due to many factors, such as operating loads, fatigues, and corrosions. Undetected damage can result in some catastrophic failures, which is very costly in terms of human life and property damage.

对于各种服役的工程结构，在其外部环境的作用下，都将会产生结构内部的物性损伤，而这些损伤往往具有很大的危险性，会导致结构物倒塌或者失效，从而造成巨大的经济损失。
