Effect of Vertical Loads on the Lateral Bearing Behavior of PHC Pipe Piles

摘要：

Pile foundations are often subjected to both vertical and lateral loads. The current design practices assume that the effect of these two loads is independent of each other and hence the pile design is carried out separately for vertical and lateral loads. By considering the initial stress of soil and the contact between pile and soil, the effect of vertical loads on the lateral response of piles is brought out through 3-dimensional finite element model validated by the field test results, the influences of the parameter of the soil, the unconstrained length of the pile have also been studied in the paper. The simulation analyses show that the presence of vertical load decreases the lateral deflection.
