Abstract
Pada beberapa kasus pendesainan pondasi di atas tanah
lunak, penggunaan pondasi tiang pancang menjadi salah satu
pertimbangan yang dipilih. Namun, penggunaan jenis pondasi
tersebut relatif sangat mahal jika dibandingkan dengan biaya
pembangunan struktur gedung itu sendiri khususnya apabila
kedalaman lapisan keras pada tanah dasar relatif dalam. Apabila
gedung tersebut merupakan sebuah gedung tinggi, maka pondasi
yang digunakan adalah pondasi tiang pancang mencapai tanah
keras, maka biayanya akan lebih mahal lagi. Pada studi ini,
dilakukan analisa terhadap struktur gedung secara simetris 3
dimensi setinggi 4 dan 6 lantai yang dibangun di atas tanah lunak
Surabaya dengan kedalaman tanah keras mencapai 20 meter
menggunakan pondasi dalam tiang pancang. Beberapa masalah
yang harus dipecahkan adalah :a) Bagaimana hasil pondasi tiang
pancang yang dibutuhkan pada perhitungan dengan metode
konvensional dan p-y curve pada tumpuan end bearing dan friction.
b) Bagaimana pengaruh pondasi tiang pancang metode
konvensional dan p-y curve pada tumpuan end bearing dan friction
terhadap struktur atas gedung. c)Bagaimana hasil perbedaan nilai
biaya bahan yang dikeluarkan dari masing-masing metode dan
tumpuan. Hasil dari studi ini didapatkan suatu kesimpulan bahwa
vi
perencanaan struktur bangunan gedung yang paling hemat yaitu
menggunakan metode p-y curve dengan Pijin sebesar 0,9 ultimate
tumpuan end bearing.

In some cases designing foundations on soft soil, the use of
pile foundation became one of the considerations is selected.
However, the use of the type of foundation is relatively very
expensive when compared to the cost of construction of the building
structure itself, especially when the depth of the hard layer on a
relative basis in the soil. If the building is a tall building, the
foundation used is a pile foundation reach hard ground, then the cost
will be more expensive. In this study, an analysis of the structure of
the building is symmetrical 3-dimensional high as 4 and 6 floors are
built on soft ground Surabaya hard soil to a depth of 20 meters deep
using deep foundation piles. Some of the problems to be solved are:
a) How do the results of pile foundation is needed in the calculation
by the conventional method and py curve at the end pedestal bearing
and friction. b) How does the influence of pile foundation
conventional method and p-y curve at the end pedestal bearing and
friction of the upper structure of the building. c) How do the results
of differences in material costs incurred value of each method and
the pedestal.Results from this study obtained a conclusion that the
structural design of the building is the most economical method with
Pijin py curve of 0.9 ultimate end bearing pedestal.
