AXIAL LOAD CAPACITY OF PILES IN CALIFORNIA IN COHESIONLESS SOILS. IN: CURRENT PRACTICES AND FUTURE TRENDS IN DEEP FOUNDATIONS

The literature abounds with methods to estimate the axial tensile or compressive load capacity of driven piles. Most of these methods have disadvantages associated with undue complexity, non-linear relationships, lack of sufficient support load test data, use of out-of-date technology, or simply lack of desired accuracy. The California Department of Transportation performed a series of load tests on driven piles for bridges, over a period of years, but lacked the kinds of soil information needed to extend their experience to new sites, and did not have the data in easily accessible forms. A project was initiated to make new soil borings and cone soundings at a number of sites and to incorporate data into an electronic database for ready access. There was a further interest in examining the accuracy of existing methods for predicting capacity and of developing estimation procedures that were fitted to experience in California. This paper is concerned with pile tests in cohesionless soils, ranging from silts through clean sands, but excluding sites with soils classified as gravelly sands or coarser. Experience indicates that the margin of error for predictions in cohesionless soils is substantially in excess of that for cohesive soils. The considered pile types are one-end and closed-end steel pipe piles and precast concrete piles. H piles were included in the investigation but they all encountered gravels and are thus excluded from this paper.
