Abstract:
Foundation is very important for building as foundation is the lowest part of the
building that transmits the building load to the soil or rock that is on the ground underneath.
This study aims to determine the comparison of ultimate bearing capacity of bore pile
foundation using several methods. Based on CPT data using Aoki & De Alencar method,
the ultimate bearing capacity for bore pile foundation with diameter 80 cm are 187.74 ton
and 339.76 ton, with diameter 100 cm, the ultimate bearing capacity are 285.17 ton and
522.53 ton. Using Meyerhoff method on CPT data, the ultimate bearing capacity for 80 cm
diameter foundation are 986.96 ton and 767.05 ton, for 100 cm diameter foundation, the
ultimate bearing capacity are 1542.12 ton and 1198.51 ton. Based on SPT data using
Reese & Wright method, the ultimate bearing capacity are 994.26 ton and 921.76 ton for
80 cm diameter and for 100 cm diameter are 1861.53 ton and 1628.89 ton. The ultimate
bearing capacity using Luciano Decourt method are 1361.54 ton and 1192.98 ton for 80
cm diameter. For 100 cm diameter, the ultimate bearing capacity are 1861.53 ton and
1628.89 ton. Lastly, there is O’Neill & Reese method which have 569.23 ton and
584.22 ton for 80 cm diameter, 729.77 ton and 749.55 ton for 100 cm diameter. The
interpretation of Static Loading Test from Chin method has an ultimate bearing capacity
952.38 ton. The interpretation of Static Loading Test from Mazurkiewicz method have
lower ultimate bearing capacity than Chin method which is 800 ton.
