Abstract

This study compares the axial bearing capacity and settlement of bored 
pile foundations at the Terban Renovation project in Yogyakarta, using 
manual analytical methods and PLAXIS 2D numerical simulation. Soil 
parameters were obtained from Standard Penetration Test (SPT) data. 
Bearing capacity was calculated using Meyerhof's (1976) method, while 
pile group settlement was estimated using Vesic's (1977) method. The 
manual calculation produced an ultimate group bearing capacity of 
4,778.449 kN for both column labels 123 and 143. PLAXIS 2D yielded 
lower values of 9576,71 kN for label 123 and 13144,3 kN for label 143, 
indicating that the numerical simulation provides more conservative 
bearing capacity estimates. This difference reflects how each method 
models soil-pile interaction and failure mechanisms. For settlement, the 
manual method gave 0.0053 m for both labels, while PLAXIS 2D returned 
0.0096 m for label 123 and 0.0298 m for label 143. The variation between 
labels in the PLAXIS results is due to different axial loads at each column 
location, derived from the ETABS structural analysis. All settlement 
values satisfy the allowable limit for high-rise buildings under SNI 
8460:2017 (s < 15 cm + b/600), confirming that the foundation design 
meets deformation criteria under the applied loading conditions.
