中文摘要近年来为使土地之有效利用，大型土木结构、高层建筑物之兴建且在有效率的机械开发之下，广泛的使用桩径大、桩身长之基桩做为深基础已成为一种趋势，为有效了解基桩承载力，大抵以基桩载重试验来验证基桩设计承载力是否足够。

Better numerical prediction of the distributions of shear forces and bend moment within the pile group has also been obtained with the consideration of many stochastic parameters such as the soil properties of sea warf, seismic properties, etc. And then we analyze the dynamic nonlinear seismic pile-soil interaction in sea warf as an example to apply the software of ANSYS to the assessment of the dynamic interaction of soil-structure in the harsh situation of random earthquake. And then we denoted that the soil-pile interaction is too difficult to be expressed in equations because the non-linear interaction between soil and pile.

5桩基由于其本身的优点得以在海洋码头结构中大量的运用，但是海洋码头结构在海洋环境下受多方面的影响，土与桩体的相互作用关系很难清楚的表达，由于影响因素的多样性及复杂性，以及它们与桩基性状之间的非线性和非确定关系，使得关于桩基性状的各种理论解答还不能采用简便的表达式以反映其复杂多变的机理，尤其是难于反映施工及环境因素对桩基性状的影响，而且如何发挥桩基的技术经济效益和如何合理的确定桩的极限承载力，也是一个技术难度很大的问题。

The residual stress in bent pile can be ignored. The curvature of batter pile has important influence on additional moment to bent pile under vertical load on top. When the radius of curvature on the upper segment of pile is small, the additional moment can not be ignored.

得到以下结论：桩体由于施打而发生的弯曲在桩体中产生的残余应力可以忽略不计；桩顶竖向荷载作用下桩身的弯矩同桩的偏斜曲线有重要关系，桩顶处的曲率较大时，桩身的弯矩在工程中是不能忽视的。

First, the computation theory of the anti-sliding pile has been researched including interaction between the pile and tho landslide, the mechanical model of the pile and the calculation method of the internal force of the pile with prestressed anchor cable. Second, the internal force status, the mechanical computation model and the design method of the foundation beam with prestressed anchor cable have been analyzed. Finally, by the example, engineering instance and the geology mechanical model test, the main results and conclusions deduced from the thesis have been compared and validated.
