Ngawi Toll Road which includes an access road along 1040 m and 1 overpass intersection with a total length of 86.16 m, a width of 17.80 m and consisting 0f 3 spans. Based on data from soil investigation, the construction of this overpass bridge was built on hard soil. The purpose of this final project is to analyze the bearing capacity of the deep foundation, where the dimensions of the structure, number of piles and depth are in accordance with the DED plan. The research is focused only on structural elements of Pier 1 and the foundations used is bore pile foundation which totaling 16 pieces with 14 m depth. Based on the results of the foundation analysis on pier 1, the group pile efficiency value (Eg) = 0.67, the axial allowable bearing capacity for 1 pile (Pallow) = 1675 KN, and the lateral allowable bearing capacity (Hallow) = 231.9 KN. As for the forces acting on the foundation, the maximum axial force carried by 1 pile (Pmax) = 1641 KN < Pallow, the minimum axial force (Pmin) = 649.3 KN > 0.0, and the maximum lateral force (Hmax) = 217.4 KN < Hallow. From the results of this calculations, it can be concluded that the pier structure of the overpass bridge of interchange Sragen Timur using a bore pile foundation of 16 pieces and 14 m depth is safe enough to carry axial loads, pull loads and lateral loads. Key words : axial load of pile, lateral load of pile, bore pile, bearing capacity of deep foundation.} }
