Penggunaan Sheet Pile Sebagai Perkuatan Tebing Sungai Dondang Di Lokasi Proyek Blc2 Pt. Kutai Energi, Kabupaten Kutai Kartanegara, Kalimantan Timur

Abstract

<p>The collapse of the banks of the Dondang river at the BLC2 project site of PT. Kutai <br />Energi caused the barge to not dock and the conveyor to be unusable. One of the <br />causes of landslides is changes in river water levels which cause the soil around the <br />river banks to become saturated and unstable. The research begins with a survey <br />and data collection related to the research location. Analysis using GeoStudio <br />(Slope/W) 2012 software was carried out with two models, namely when the river <br />water level is normal and when the river water level is in a flooded condition. The <br />results of the analysis show that the critical condition occurs in the second condition <br />where the river water level is in a flood condition. In these conditions, it is known <br />that in the existing condition of the slope without reinforcement, the value of safety <br />number (SF) = 1.125 is obtained. On the other hand, when the pile reinforcement is <br />given, the slope safety score increases to 1.741 which indicates that the plaster can <br />overcome the sliding on the cliff due to the influence of the river water level</p>
