简介：一个pile-soil-structureinteraction系统的地震抵抗的表演上的学习是在土木工程学实践的一个相对复杂、首先重要的问题。在这篇论文，为pile-supportedstructures的一个计算模型和计算过程，它能按时地考虑堆积土壤相互作用完成，被有限单元法建立。数字实现在时间领域被做。为pile-soil-structure系统的地震反应分析的简化近似简短被介绍。然后，比较研究为一个设计例子被执行，数字结果由有限单元法和简化方法分别地计算了。通过比较分析，简化方法获得很好的结果同意有限单元法完成的那些，这被显示出。数字结果和调查结果将为有启发性的指南提供支持堆积的结构的forearthquake抵抗的分析和设计。

简介：这份报纸论述基于的一个人工的神经网络(ANN)能被用来预言c-的失败概率的反应表面方法与空间地可变的土壤倾斜。在这个方法，拉丁hypercube采样技术被采用为建立一个ANN模型产生输入数据集；随机的有限元素方法然后被利用就土壤性质的空间可变性而言计算相应输出数据集；并且最后，一个ANN模型被训练构造失败概率的反应表面并且获得合并相关变量的近似功能。说明例子的结果显示建议方法提供失败概率的可信、精确的评价。作为结果，获得的近似函数能在c-斜坡可靠性分析被用作特定的分析进程的一种选择。
