Abstract:

Data were taken during the lateral loading of single 600mm diameter test pile installed at a site where the soils consisted of clean fine cohesionless soil to silty fine cohesionless soil. Two types of loading were employed, static loading and cyclic loading. The data were analyzed and families of curves were developed which showed the soil behavior presented in terms of the lateral soil resistance p as a function of pile deformation y. With theoretical studies as a basis, a method were derives for predicting the family of p-y curves based on the properties of cohesionless soil and pile dimensions. Procedures are suggested for both static loading and cyclic loading. While there is some basis for the methods from theory, the behavior of cohesinless soil and around a laterally loaded pile does not yield to a completely rational analysis therefore, a considerable amount of empiricism is involved in the recommendations. The procedure was employed for predicting p-y curves at the experimental site and computed results are compared with experimental results. The agreement is good.
