MECHANICAL BEHAVIOR OF PILE FOUNDATIONS SUBJECTED TO CYCLIC LATERAL LOADING UP TO THE ULTIMATE STATE

摘要

Pile foundations in a soft ground will usually be subjected to lateral cyclic loading during earthquakes. In a major earthquake, it is reasonable to thick that the mechanical behavior of the pile foundation and the surrounding ground is nonlinear. In recent years, the limit state design method has become predominant in the design of foundations for railway bridges and other structures. Investigations of the mechanical behavior of pile foundations subjected to later- al cyclic loading up to the ultimate state, therefore, are very important in providing evidence for the design method.
