PERENCANAAN DINDING PENAHAN TANAH GARDU INDUK 150 KV KECAMATAN TENGGARONG KABUPATEN KUTAI KARTANEGARA KALIMANTAN TIMUR --Ed. 1

ABSTRAK
Perencanaan dinding penahan tanah (DPT) di Kelurahan Timbau Kecamatan Tenggarong
Kabupaten Kutai Kartanegara. Kondisi memiliki lereng yang terindikasi terjadi
longsor.Perhitungan ini bertujuan untuk menentukan tipe DPT yang sesuai,menentukan
dimensinya,menghitung stabilitas geser, stabilitas guling, stabilitas daya dukung tanah,
stabilitas kelongsoran,tiang bor serta menghitung penulangannya.Perhitungan stabilitas
lereng menggunakan metode irisan Fellinius (1927), koefesien tekanan tanah
menggunakan teori Coulomb, daya dukung tanah menggunakan teori Terzaghi (1943),
perhitungan tiang bor menggunakan metode Meyerhof (1976;1983) dan penulangan
menggunakan SNI 03-2847-2002.Ketinggian lereng mencapai 9,4 meter, maka DPT tipe
kantilever dengan model trap dengan dimensi trap 1, H = 6,0 m, B = 4,2 m dan D = 0,6 m
dan dimensi trap 2, H = 6,0 m, B = 4,2 m dan d = 0,6 m. Didapatkan nilai trap 1 yaitu
FK
geser = 1,512 ; FKguling = 1,838; FKDDT = 2,778 dan Didapatkan nilai trap 2 yaitu FKgeser =
1,507 ; FKguling = 1,899 ; FKDDT =2,844.Digunakan pondasi tiang bor untuk memperkuat
daya dukung tanahnya dengan diameter trap 1 = 0.4 m dengan panjang = 8 m dan diameter
trap 2 = 0.4 m, dengan panjang = 4 m. Bahan material yang digunakan adalah beton
bertulang untuk kedua trap dengan tulangan momen D22 mm dan tulangan bagi D13.
Kata kunci : dinding penahan tanah, kontrol stabilitas,tiang bor,penulangan beton.
ABSTRACT
Planning of retaining wall (DPT) in Timbau Village, Tenggarong District, Kutai
Kartanegara Regency. The condition has a slope that indicated landslides. This calculation
aims to determine the appropriate type of retaining wall, determine its dimensions,
calculate shear stability, rolling stability, soil bearing capacity stability, landslide stability,
drill pole and calculate its reinforcement. Calculation of usage using Fellinius slice
method (1927), the coefficient of soil pressure using the Coulomb theory, the carrying
capacity of the soil using the theory of Terzaghi (1943), the calculation of the drill pole
using the Meyerhof method (1976; 1983) and reinforcement using SNI 03-2847-2002. The
slope height reaches 9.4 meters, then DPT cantilever type with trap model with trap
dimension 1, H = 6.0 m, B = 4.2 m and D = 0.6 m and trap dimension 2, H = 6.0 m, B =
4.2 m and d = 0.6 m. The trap value 1 is obtained, namely the safety factor shear stability
= 1,512; Safety factor bolster stability = 1,838; Safety factor stability Soil carrying
capacity = 2.778 and Trapping value 2 obtained, namely safety factor shear stability =
1.507; Safety factor bolster stability = 1,899; Safety factor stability Soil carrying capacity
= 2,844. A bored pile foundation is used to strengthen the carrying capacity of the soil
with a trap diameter of 1 = 0.4 m with length = 8 m and trap diameter 2 = 0.4 m, with
length = 4 m. The material used is reinforced concrete for the second with a reinforcement
trap with D22 mm moment and reinforcement for D13.
Keywords: retaining wall, reinforcement control, drill pole, concrete reinforcement
