Studi Daya Dukung Pondasi Dangkal pada Tanah Gambut dengan Kombinasi Geotekstil dan Grid Bambu
Abstract. The construction on peat soil have many problems, Two significant problems are low bearing capacity and high construction settlement. The usage of grid bamboo and geotextile as a composite system is expected to overcome those problems. The purpose of this research is to check the relationship of bearing capacity with depth of the reinforcement layer, width reinforcement layer and spacing of reinforcement layers between of grid bamboo and geotextile, and to the angle of stresses distribution. The difference of the bearing capacity between unreinforced soils and reinforced soils referred as Bearing Capacity Ratio (BCR). From study model at laboratory the result indicate that maximum BCR is 4.32 at ratio L/B, d/B and s/B are increasing 3, 0.25, and 0.5. Maximum the angle of distribution is 78.79° at L/B and d/B (B is width of footing) are increasing 4 and 0.25. The increasing of BCR and angle of stress distribution is proportional by the increasing of reinforcement dimension and it diversely correlated with depth of reinforcement.
