Abstract

There are several methods of calculating pile load capacity. One of the most accurate, costly and difficult of these methods is to do a pile loading test. The least accurate and costly method to predict the pile load capacity is the use of the theoretical static formula based on soil properties determined from the laboratory tests. Using in-situ tests such as static cone test (CPT) to determine the pile load capacity is considered to be average cost and easy to implement, and its results are appropriate. In this research, pile load tests were performed on seven (7) piles in the site of the construction of "2760 Residential and Social Units" in Alsalam area in Port Saied City, Egypt. The pile load tests were conducted up to load of 2000kN which was 2.5 times the design load. Also, three (3) static penetrometer tests (CPT) were performed to depths of 25 m below the existing ground surface at the site. Six methods were used to analyze the pile loading tests data. These methods were: Davisson, Brinch Hansen, Chin-Kondner, Decourt, Mazurkiewicz's and DeBeer. Two methods were used to predict pile load capacities from CPT test results. The first one was Bustamante and Gianeselli (LCPC) as a direct method whereby the measured readings are scaled up for evaluation of full-size pilings. The second was the DIN-4014 as an indirect method via indirect CPT assessments of shear strength parameters. The pile load capacities predicted from pile load tests were discussed and compared with those predicted from CPT tests.
