Experiment-4: Quasi-static Tests in Improved Soil (TPI)
Experiment Type: Field
Description: Experiment was performed on October 20, 2010 in Miami, Oklahoma. A full geotechnical site evaluation was performed and provided in the documentation folder. A circular pipe pile with a diameter of 12.75", a sidewall thickness of 3/8", and a length of 23' was installed in the center of a 13'x13'x13' cement deep soil mixing (CDSM) improved soil block. The pile cap was subjected to lateral quasi-static loads at a maximum rate of 0.2 inches per second. Several cycles were applied at increasingly higher levels of displacement. A maximum displacement of 8 inches was achieved before the critical region at the base of the pile above the improved ground experienced buckling and fracture due to low cycle fatigue. A hydraulic actuator from Iowa State University (ISU) was used to apply the loads.
