Analisis Stabilitas Lereng Dengan menggunakan perkuatan Solder Pile
(Studi kasus : Ruas Jalan di Papua Barat)
Abstract
West Papua Province is the result of division from Papua Province in 2005. West Papua's natural conditions consist of mountains which cause roads to be in areas prone to landslides. Therefore the author feels the need to analyze the stability of the slopes on the side of the road. In this analysis, the first thing to do is to check whether the existing condition of the slope is stable or not, then do a back analysis to get the design condition parameters. The design parameter is used to determine the reinforcement of the slope. The reinforcement used is solder pile which is used to cut the sliding plane of the slope. Based on the strengthening analysis using a solder pile without disturbing the groundwater level, the safety factor is 2.37 and if there is influence from the groundwater level, the safety factor is 1.3, the safety factor value above shows that the slope is stable with reinforcement using a solder pile.
