Effect of Compressive Load on Uplift Capacity of Cast-Insitu Bored Piles

Technical note


Field tests were conducted to study the effect of compressive loading on the uplift capacity of single piles embedded in silty sand. The test program consists of four instrumented cast in situ axial pile load tests in compression, pure tension and tension with 25 and 50% of compressive load of ultimate capacity in compression. The experimental results indicate that the net ultimate uplift capacity of single pile decreases with increase in compressive load. The shaft friction is non linear in nature. It observed that as the compressive load increases the shaft friction along the length of pile decreases.
