... The purpose of this paper is to provide guidelines for writing a performance specification for the construction and load testing of stone columns in cohesive soils. Specifications from five different sources, three specialty contractors and two agencies, were studied to develop the guidelines...

... 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...

.... Anchors were installed in the center hole, with rods extending to the surface. The top of the piles were loaded in increments to 3½ times the design load to overcome the loss of load into the thick clay layer. A procedure of performing the load test a short time after the pile was driven and cyclic...

... Pipe piles and H-sections about 35 m (115 ft) long were driven through 24 m (80 ft) of alluvial materials to bearing in a stratum of glacial till about 15 m (50 ft) thick overlying bedrock. Load tests were conducted to establish the equipment and driving resistance needed to develop a capacity...

... Load transfer mechanisms in 17 test piles are evaluated by means of an extensive monitoring program during full-scale load testing and are compared with behavior computed by a displacement compatibility analysis. H-piles, Raymond step taper piles, auger-cast piles, and steel pipe piles were...

... The use of methods of prediction of the performance of deep foundations is strongly encouraged. The paper presents models for both axially loaded and laterally loaded deep foundations and shows examples of the use of the models. Internal instrumentation that can be used in future load tests...
