Abstract

In this study, the shaft capacity of open- end steel pile in sandy soil was evaluated using a number of full scale tensile pile load test. Mentioning the available methods of predicting the shaft resistance of the pile, the soil properties and test apparatus, the results obtained from pile loading tests was presented. In the present study, 7 piles with constant diameter of 1.20m with different length of 4.20m up to 4.80m have been loaded. The earth pressure coefficient and frictional angle at the soil-pile interface were evaluated. The results of the study showed that for this method of pile installation, frictional angle in the soil-pile interface is 0.52 times of frictional angle of soil and the earth pressure coefficient reduces considerably.
