Pengaruh Tanah Timbunan Terhadap Daya Dukung Pondasi Telapak (Square Footing)

The lower structure of a building construction consists foundation and layer soil to support the load upper construction. condition under is closely related behavior itself when it receives loads, for example failures that occur in sub-grade embankment foundation, namely too soft so carrying capacity withstand small, as result settlement occurs large. So must be strong, stable, safe, does not decrease, break, because will difficult repair system. purpose this study was determine effect on footing how much caused foundation. Plaxis D2 V20 method finite element aims analyze design geotechnical field. Soil samples were taken at hospital. Wulan Windi, Medan City, using manual tools. investigation nature characteristics carried out Civil Engineering Laboratory Area University State Polytechnic laboratory. results research showed density (Gs) = 2.63 gr, wet volume weight (γb) 14.8512 kN/m3, dry (γd) 0.3236 permeability ( K)= 12,929 cm/hour, shear stress (φ) 23,610 . cohesion (c) 0.057 kg/cm2, Modulus elasticity (E) 2400 kN/m2 Then from running plaxis, deformation 0.1601 meters, while Steinbrenner method, resulting decrease 0.1232 m. which causes plate tread fracture. 0.012 analysis obtained safety factor 1 (one).
