Lateral Load Tests on Bored Piles and Pile Groups in Sand
Publication: 7th FMGM 2007: Field Measurements in Geomechanics
Abstract
The lateral behavior of bored piles in sand was examined by field tests at a site in Kuwait. The soil profile consists of medium dense silty sand underlain by dense to very dense sand with silt. Two single piles and two small groups each consisting of two piles were installed and load tested to failure. All piles were 0.3 m diameter and 5 m deep. One single pile was instrumented with electric resistance strain gages to measure the bending strains during the lateral load test. The pile groups were installed in two perpendicular directions and were load tested against each other to determine the influence of the loading direction on the lateral capacity. Test results indicate that the load deflection response is nonlinear. Both the ultimate lateral capacity and the deflection at working loads were examined. The response of the pile groups compared to the single piles was determined. Test results on the groups indicate that the direction of loading has a significant influence on the group behavior under lateral loading.
