ABSTRACT
Bored Pile foundation is one of the most important elements in construction which plays a role in distributing the heavy load of the building concentrated on the column to the harder soil layer areas to achieve structural stability. This study aims to calculate and compare the carrying capacity of Bored Pile from SPT data using the Reese and Wright method, CPT data using the Meyerhof method, single pile settlement using the Poulos and Davis method as well as allowable settlement and calculating the group pile settlement that occurs. Based on SPT data using the Reese and Wright method, the ultimate bearing capacity of pile P219 with a depth of 26.9 m is 699.599 tons, P235 at a depth of 21.5 m is 413.559 tons and P317 at a depth of 22 m is 413.559 tons. Based on the CPT data using the Meyerhof method, the ultimate bearing capacity on the S-01 data is 1519.1517 tons at a depth of 13.20 m and the S-05 data is 372.5296 tons at a depth of 13.20 m. The decrease in the single pile that occurred in P219 was 3.3976 mm, P235 was 5,6628 mm and P317 was 5.7646 mm. The allowable drop is 80 mm. The decrease in pile group on PC22 is 1.98 mm, PC12 is 7,81 mm and PC3 is 19,7 mm. The dimensions of the Pile Cap size are enlarged to increase the efficiency of the pile group in order to minimize the pile group settlement that occurs.
Key words : Foundation, Bored Pile Bearing Capacity, SPT, CPT, Pile Settlement.
