Analisa Perhitungan Dinding Penahan Tanah pada Proyek Pembangunan Parkiran Masjid Agung Medan (Studi Kasus)

Abstract

Soil Retaining Wall is one of the soil control techniques that is very necessary to maintain soil stability and prevent soil collapse beside the Basement. Cantilever walls (consoles) are reinforced concrete walls that use console action to hold the mass behind the wall from the natural slope that occurs. The planning of the retaining wall carried out in the Medan Great Mosque Parking Project is a planning of recommended cantilever retaining walls for medium height walls. The purpose of this study was to analyze the calculation of retaining walls in the Medan Great Mosque Parking Project. The purpose of this study was to determine the function of the cantilever retaining wall that was installed as a retaining wall for the basement in the Medan Grand Mosque Parking Building project and as our consideration especially users who want to plan a Ground Retaining Wall using cantilever Walls. The method used in the planning of cantilever retaining walls is a method of calculating cantilever retaining walls based on Rankine's soil pressure theory. Based on the results of the discussion of cantilever retaining walls, it can be concluded that the retaining wall is cantilever safe against rolling stability (FGL) = 19.08 and safe against shifting stability (FGS) = 2.69 and safe against collapse of soil support capacity (F) = 24,165 .
