Abstract

COMPARISON OF PILE FOUNDATION SUPPORT WITH STATIC METHOD AND MEH ANALYSIS METHOD TO PDA TEST ON PIER OF SECTION 4 OVERPASS BRIDGE AT TOLL OF PEKANBARU-DUMAI SAPRIADI 153110612 ABSTRACT: A foundation plan is said to be correct if the load transmitted by the foundation to the ground does not exceed the strength of the soil concerned. This thesis will discuss the analysis of bearing capacity and pile safety factors to determine the comparison of the results of each method with results PDA test and see the most effective method to use. The method used in this study used a static method with the method of Luciano Decourt, Resee and Wright and Briaud et al for the 2D Finite Element method using 2D Plaxis with axisymmetric models. The four methods are used to calculate the bearing capacity and the safety factor of P07 and P25 piles and then compared for the carrying capacity and safety factor values for the PDA test. The results of this study indicate a comparison of the bearing capacity and the safety factor of a single pile foundation on P07 and P25 piles. For the bearing capacity of the pile using a static method for the Luciano Decourt method 4900.80 kN, Reese and Wright 4553,555 kN and Briaud et al 4965.23 kN and MEH 2D for P07 of 4074.88 kN, for P25 of 4084.00 kN shows the results that the carrying capacity with MEH 2D has a value closer to the PDA test results, namely for P07 2696.84 and P25 2726.26 kN. For the safety factor on the P07 and P25 poles using the Luciano Decourt method 2.65 and 2.69, Resee and Wright 2.47 and 2.49, Briaud et al 2.69 and 2.72, MEH 2D pole 2.21 and 2.24 while PDA test 1.46 and 1.49. Of the five analysis methods, the FEM calculation is the method with the closest analysis results to the PDA test both from the analysis of the carrying capacity and the safety factor of the foundation.
