PERHITUNGAN DAYA DUKUNG TIANG PANCANG METODE LUCIANO DE COURT
(Berdasarkan Data Boring SPT)DATA PERENCANAAN :Data Tanah = Kedawung B-1Project = Pembangunan Gedung Kedawung Galery
Jenis Tiang Pancang = BulatDiamater Rencana Tiang Pancang
= 40 cm
Luas Penampang Dasar Tiang (Ap)
= 1256.64 cm2 = 0.12566 m2
Keliling Selimut Tiang yang Terbenam (As)
= 125.664 cm = 1.25664 m
SF = 3
Rumus yang dipakai adalah
QL = QP + QS
Dimana ,
QL : Daya dukung tanah maximum pada pondasi
QP : Resistance ultimate di dasar pondasi
QS : Resistance ultimate akibat lekatan lateral
QP = qp x Ap =( Np x K ) x Ap
Dimana,
Np : Harga rata – rata SPT disekitar 4B diatas hingga 4B dibawah dasar tiang pondasi
( B adalah diameter pondasi ),
K : Koefisien karakterisitik tanah
Nilai KJenis Tanah
t/m2
12 lempung
20 lanau berlempung
25 lanau berpasir
40 pasir
Ap : Luas penampang dasar tiang
qp : Tegangan diujung tiang
Qs = qs x As = ( Ns / 3 + 1 ) x As
Dimana,
qs : Tegangan akibat lekatan lateral dalam t/m2
Ns : Harga rata – rata SPT sepanjang tiang yang tertanam dengan batasan 3 < N < 50
As : Luas selimut tiang sepanjang tiang yang terbenam
Berikut ini table perhitungan daya dukung pondasi dengan metode Luciano Decourt :
A. Diameter rencana tiang pancang 40 cm
B. Ukuran rencana tiang pancang 45 x 45 cm2
C. Diameter rencana tiang pancang 50 cm
D. Diameter rencana tiang pancang 60 cm
A. Diameter rencana tiang pancang 40 cm
Jenis Tiang Pancang = BulatDiamater Rencana Tiang Pancang = 40 cm
Luas Penampang Dasar Tiang (Ap) = 1256.64 cm2 = 0.12566 m2
Keliling Selimut Tiang yang Terbenam (As)
= 125.664 cm = 1.25664 m

Kesimpulan Daya Dukung Tiang Pancang dengan Metode Luciano Decourt
a. Semakin besar ukuran diameter tiang pancang maka semakin dangkal kedalaman yang dibutuhkan untuk menahan beban yang sama
b. Dengan kebutuhan P ijin 100 t memakai tiang pancang bulat ukuran diameter 60 cm, maka kedalaman minimal yang harus dipenuhi adalah 19,5 m untuk mampu menahan P ijin.
PERHITUNGAN DAYA DUKUNG PONDASI DENGAN METODE VAN DER WEEN
Daya dukung nominal total sebuah tiang pancang adalah
QN = ( Qp )a + ( Qs )
Yang terdiri dari unsure perlawanan tanah di ujung tiang dan lekatan ( friction ) disepanjanh tiang.Unsur perlawanan tanah di ujung tiang dirumuskan sebagai berikut :
( Qp )a = (qc)m x Ap / 3
Dimana :Ap : Luas penampang ( section ) ujung tiang3 : Angka keamanan unsure Qp : Koefisien, yang tergantung dari jenis tanah dan tiang yang dapat dilihat pada table di bawah ini
Tanah qc (kg/cm2) Very soft s/d Medium
Clay 0-50 1.5 40
Stiff s/d hard clay > 50 1.1 100( qc )m : harga rata – rata conus disepanjang 3,5B diatas dasar pondasi hingga B dibawah dasar pondasi
Unsur Lekatan :
Dimana,qs : qc /P : Keliling tiang2 : Angka keamanan unsure Qs : Koefisien untuk lekatan
Beriktu ini adalah perhitungan daya dukung tiang dengan metode Van Der Ween

Kesimpulan Daya Dukung Tiang Pancang dengan Metode Van Der Ween
A. Dengan metode Van Der Ween untuk menahan P ijiin sebesar 100 t, tiang pancang bulat diameter 40 cm, persegi 45 x 45 cm2, bulat diameter 50 cm, bulat diameter 60 cm tidak ada yang memenuhi sampai kedalaman 30 m.
B. Solusi dari permasalahn diatas adalah memperbesar dimensi tiang pancang.
