| dc.description.abstract | Foundation planning begins with determining the loads that will work or
be distributed from the structures above it and then proceed with the
process of determining the value of the bearing capacity of the foundation
by gathering information about soil parameters at the plan location. One
of the bridges in Section 1 of the Yogyakarta-Bawen toll road
development project is the Sangu Banyu Underbridge which is located at
Sta 72+925. To support the bridge structure, bored pile foundations are
used as structural elements at the bottom of the bridge. The bearing
capacity calculation method used is the Reese & Wright (1997) method
and the pile settlement calculation used is the empirical method. The
results of calculating the percentage difference in the settlement of the
empirical method and the PDA test are -38.90%, -44.46%, -50.01%, -
40.35%, and -45.77%. The results of these percentages indicate that there
has been a large decrease in the settlement value of the piles for all the
tested piles and the average settlement percentage is -43.90. The results
of the calculation of the percentage difference in settlement of the
empirical method and CAPWAP analysis are -6.69 %, -3.36 %, -24.46 %,
-8.90 %, and -8.36 %. The results of these percentages indicate that there
was a large decrease in the settlement value of the piles for all the tested
piles and the average percentage settlement was -10.35% | en_US |
