【Abstract】 This paper is concerned with an analytical method to demonstrate the dynamic interaction of soilpilestructure system when subjected to earthquake excition.The structure to be analysed is an artificial island model with deep ground pile foundation. By using a numerical example,the importance of soil layer which exerts a force on the pile varying along the pile length is pointed out together with the soilpile structure inertial interaction in the structure response.Also examined is the applicatility of the assuming model through the comparison between the data of the test and finite element analysis.更多还原
