This research program considers dynamic structure-pile-soil interaction. It has two main objectives: (1) to unify existing methodologies for the design on pile foundations and then to compare the results of these predictive methods with the observed behavior of building foundations in Mexico City that experienced various degrees of damage; (2) to improve the understanding of the response of both friction and end-bearing poles to earthquake shaking, with the goal of developing more rational methods of design. Specifically, the program will attempt (1) to develop an analytical model to predict the response of pile foundations, and (2) to conduct an experimental program in Mexico City consisting of laboratory investigations and field observations.

本研究方案考虑结构-桩-土动力相互作用。主要有两个目标：(1)统一现有的桩基设计方法，然后将这些预测方法的结果与墨西哥城经历不同程度破坏的建筑基础的观察行为进行比较；(2)提高对摩擦杆和端承杆在地震作用下的响应的认识，以发展更合理的设计方法。具体来说，该项目将尝试(1)开发一个分析模型来预测桩基的响应，(2)在墨西哥城进行一个实验项目，包括实验室调查和现场观察。
