LATERAL PERFORMANCE OF HOLLOW BAR MICROPILE IN COHESIONLESS SOIL
Maged Abdlrahem, M., Hesham El Naggar, F., and Wenbing Wu
Hollow bar micropiles are increasingly used to support a variety of structures due to their fast installation and effective load transfer due to associated ground improvement. However, their lateral capacity is relatively small due to their small cross – sectional area. In this study, a full–scale micropile was installed in cohesionless soil and was subjected to monotonic lateral load test. The micropile was 115 mm in diameter and 6m in length. The soil at the test site was medium dense to dense sand. The test results are presented and discussed in terms of load – displacement curve. In addition, the micropile behavior during the test was analyzed numerically utilizing the program LPILE and the results are compared to the load-horizontal displacement curve obtained from the full-scale load test.
