| dc.description.abstract | Pile foundations is one used to transfer the structural loads to soils. The application of
concrete driving pile is usually a greater preference due to it's ability to withstand on
pulling stresses in the course of lifting, transporting and driving. A prestressed concrete
pile is a type of popular pile suitable to massive production such as prestressed spun
concrete pile produced by using concrete and high strenght steel by an actual designing
method. Thus this sort of pile can result in a great financial efficiency.
The objective of this thesis will be to calculate the bearing capacity, settlement, and the
effect of geological condition on bearing capacity and settlement of pile, using finite
element Plaxis program, and the result is compared to loading test. In addition being
compared to loading test, it is also compared to bearing capacity of calculation result of
field and laboratory data. This research is conducted in piles on locations of P 1, BS, P2,
P3, P5, P6, P7, P9, Pl 1, and Pl3.
From the result of calculation by working load through Plaxis program, it is same as
working load on loading test: 1) The threshold ultimate bearing capacity (ultimate output)
of Plaxis program in locations mentioned above is less than loading test. 2) Output of
Plaxis program in locations P2, P5, P7, and P9 indicates significant settlement compared
to loading test. 3) Pennanent settlement in locations Pl, P3, and P6 from output of Plaxis
program is less than the result of loading test. 4) Maximal settlement during maximum
loading from output of Plaxis program in locations P3 and P6 is less than loading test. 5)
Maximal rebound of elasticity in locations P3 and Pl I of Plaxis program output is less
than result of loading test. 6) Permanent settlement, maximql settlement during maximal
loading and maximal rebound of elasticity tends to be less toward upstream of river
Percut. 7) The concrete driving pile is shorter toward upstcam of river Pcrcut largely due
to effect of geological condition in which the depth of clay soil is thinner progrcssivdy.
Conclusion of the calculation is that permanent settlement, maximal rebound of elasticity,
maximal settlement during maximal loading of all piles observed is in variation, some is
larger, and some is smaller than loading test. The values of settlement tend to be smaller,
while supporting force tends to be larger toward upstream ofriver Percut. | en_US |
