Analisis Daya Dukung Fondasi Tiang Dengan Perkuatan Model Sayap Pada Tanah Lunak
ABSTRACT
Advancements in science and technology of civil engineering have led the
development of modifications to the shape of pile foundation. Modification of the
pile foundation by adding wings to the pile is one way to increase skin friction on
soft soil, so that a greater bearing capacity is obtained. In this research, piles
were modeled with variations of wing’s lengths of 0.50D, 0.75D, 1.00D, and
1.25D, the distance between wings also varies from 3D, 6D, and 9D. Constant
Rate of Penetration (CRP Test) will be used as a method for loading test. The
bearing capacity based on loading test data will be analyzed using Terzaghi and
Peck method. In addition, individual bearing method and rectangular shear
method were also used as empirical method to determine bearing capacity of
winged foundation. Analysis results showed that winged foundations were able to
bearing greater loads than normal piles. The largest pile bearing capacity occurs
in pile models with wing lengths of 1.25D and distance of 3D (TS2-1.25D-3D).
Addition of wing length until 1.25D will always improve the piles bearing
capacity. Unlike wing’s length, addition of the distance between the wings until
9D not always improve the piles bearing capacity.
