... specified for the top of the heliostat foundation. Soils at the site are medium dense to very dense sands and gravelly sands. Because little data were available to predict lateral deflections of drilled piers under low-level cyclic loads, a full-scale load test program was undertaken to obtain the necessary...

... During the past two decades, the use of bored piles, or drilled piers, has been shown on several occasions to be an effective deterrent to exessive slope movements. The technique is applicable when either the resisting forces of the slope are to be decreased or the driving forces to be increased...

... Lateral load tests were performed on four 4-ft-diameter drilled piers extending through water bearing granular overburden and terminating in shale bedrock. Depth of overburden varied from 10 to 43 ft. The tests involved piers with both bell and socket bases. Electric resistance strain gages were...
