Abstract

Strengthening of peatlands is necessary to maximize development on peatlands. Peat soil has the characteristics of water-saturated soil with high groundwater face, low resistance, high compressibility, and long consolidation. Therefore, infrastructure development on peatlands requires land improvement first to improve the quality of the land's support. In this case, the reinforcement used is a combination of a pole-rack foundation or a combined pole-raft foundation with the use of the piles as reinforcement. Research on a laboratory scale was conducted with variations in the distance between piles. The values obtained from this test are the value of bearing capacity, the value of BCR (Bearing Capacity Ratio), and the percentage of increase in BCR values. The results show that the maximum bearing capacity value is in the variation of S5 with a 5 cm pile spacing of 21,712 kPa in the tangent intersection method and 36,392 kPa in the mazurkiewicz method with a 211,2% or 3x greater BCR increase percentage for the tangent intersection method and 271,1% or 3x greater for the Mazurkiewicz method than the value of support before being reinforced.
