PULLOUT TESTS OF PILES IN SAND

Pullout tests on two instrumented piles were performed in a deep deposit of sand at Mustang Island, Texas. Three pullout tests were conducted to determine the tension capacity of a pile, and to assess effects of lateral loading on pullout resistance. One pullout test was performed in a pile before lateral loads had been applied and two pullout tests followed a series of lateral loads. The steel test piles were 24-in. diameter and had an embedment length of 69 feet. The top 30 ft of the piles was instrumented with strain gages. As tension loads were applied to the piles with two manually operated jacks, strain along the pile and movement of the top of the pile were recorded. Two soil borings were made at the test site prior to pile installation. Logs of these borings and results of laboratory soil tests are presented. Test equipment and procedures are described and results in the form of strain data and load versus pile-top movement are presented. From these results, skin-friction parameters are determined. No significant effect of lateral loading on pullout resistances was noted.
