| Zusammenfassung: | Piles are used extensively to resist lateral load from earth pressure, inclined load, wind, waves, earthquakes, etc. The behavior of piles subjected to lateral loads is governed by interaction between the pile and the soil, and it is a non-linear, three-dimensional soil-structure interaction problem. Pile properties, including pile stiffness and geometry, and soil properties, i.e., unit weight, stiffness, friction angle, cohesion and the pile/soil interface, play important roles in the response of piles subjected to lateral loads.Existing methods for the analysis of laterally loaded single piles can be generally classified into the following five categories: (1) the limit state method; (2) the subgrade reaction method; (3) the p-y method; (4) the elasticity method; and (5) the finite element method. However, the effect of fundamental soil properties (e.g., strength, stiffness, and volume change characteristics) on the response of pile and soil cannot be appropriately addressed in these methods. Thus, an investigation into the effects of fundamental pile and soil properties on the soil response of a pile subjected to lateral load is necessary and helpful in improving insight into the soil/structure interaction problem for a laterally loaded pile.A fundamental study into the soil/ pile interaction response of fixed-head piles subjected to static lateral loads in sands is conducted using the non-linear finite element approach. The effects of pile properties, i.e., length and diameter, and |
