Development of P-Y Curves for Piedmont Residual Soils

摘要

P-y curves can be used to predict a piles response to lateral loading. Computer programs such as COM624 incorporate many p-y criteria which include: soft clay, stiff clay below the water table, stiff clay above the water table, sand, and vuggy limestone. A computer program can easily predict deflections and moments along the length of a pile by using known soil strength parameters. But, there is no specific criterion for producing p-y curves for residual soils; therefore accurate computer solutions predicting pile behavior to lateral loading in residual soils cannot be obtained. The behavior of residual soils cannot be captured using these other criterion for developing p-y curves. A research project was conducted at the Auburn University Geotechnical Test Site to crease a method to develop p-y curves for Piedmont residual soils.
