Abstract

Kelongsoran  terjadi  pada  ruas  jalan  Ir.  H.  Nursyirwan  Ismail,  Ring  Road  II,  kota  Sa- marinda, Kalimantan. Kelongsoran tersebut terjadi pada dua titik yang diselanjutnya akan disebut lereng 1 dan lereng 2. Tujuan dari penelitian ini adalah untuk menganalisa stabili- tas lereng dan alternatif penanganan kelongsoran menggunakan pile dan sheet pile. Data penyelidikan  tanah  digunakan  untuk  melakukan  analisa  pemodelan  kestabilan  lereng dengan metode Elemen Hingga pada program bantu Plaxis V.8.2. Hasil analisis perbaikan lereng menggunakan soldier mini pile 25x25, pada lereng 1 menghasilkan SF 2.04 dan de- formasi  26.17x10-3  m.  Sedangkan  pada  lereng  2,  didapatkan  SF  2.04  dan  deformasi 35.09x10-3  m.  Selanjutnya  untuk  perbaikan  menggunakan  flat  sheet  pile  concrete  (FCP) dengan tipe FCP-220-6S-A, pada lereng 1 menghasilkan SF 2.02 dan deformasi 28.35x10-3 m. Sedangkan untuk lereng 2, didapatkan SF 2.05 dan deformasi 37.01x10-3 m.

Abstract

Construction on the soft ground poses an excellent challenge for geotechnical engineers. Several engineering problems such as bearing capacity failure and differential settlement could occur either during or after the construction phase due to high compressibility and low shear strength. Nowadays, a number of soil improvement techniques are available to solve such problems. However, each method has its advantages and disadvantages. In this study, soil improvement analysis using pile were performed with three variations depths so called 12 m, 18 m, and 24 m from the ground level. A finite element simulation has been performed using PLAXIS 2D. The pile has been modeled as plate and Mohr-Coulomb model was used for soil model. The results show that the deeper the pile, the settlement will be decreasing. Moreover, the axial force and bending moment of the pile obtained from the output of PLAXIS 2D were also presented to assess the performance of the soil improvement technique.
