Keywords:
Numerical simulation, Pile load test, Coefficient of subgrade reactionAbstract
This research is the study of the coefficient of subgrade reaction by static pile load test, ASTM D 1143, and the finite element method Plaxis 2D. The railway bridge construction project on highway No. 226 Kanthararom - Km 145 + 000 at Km 142 + 255 to use the results to be used in the design and construction of projects or nearby areas. The bored pile is 1.00 meters in diameter and 20.00 meters long. The compressive strength designed 428.28 tons. The finite element analysis uses soil layer data from the drilling results of the borehole BH-2. The material model is elastic-plastic Mohr-Coulomb, axisymmetry and undrained analysis. It was found that both methods of settlement and coefficient of pressure resistance were close to each other, classified as hard clay, in accordance with the drilling results. In addition, the image of stress distribution and displacement shows the extent of the project affected.
