Abstract

This study aims to determine the results of the analysis of the planning of the Retaining Wall (DPT) with the Cantilever type on the high-speed train line. In addition, it is also intended to test whether the planned DPT structure can withstand dynamic loads when the high-speed train passes optimally. The data used are data from field conditions and test results such as borlog and consolidation. The analysis model used begins with manual calculations of safety stability (SF) against overturning, sliding and soil bearing capacity. Dynamic analysis was carried out using Plaxis 2D V.22 software. Based on the results of manual calculations, the SF value for shearing is 5.473> 1.8, SF overturning 5.355> 1.8 and Q toe < Qu / FS and Qheel> 0. While in the analysis of existing conditions using Plaxis assistance, the SF value is 1.770 < 1.8. Based on the results of dynamic analysis of the passing high-speed train load, with the help of the Plaxis 2D V.22 program, the maximum landslide area that occurred before being given a cantilever retaining wall was 0.6891 meters. While the maximum value of the landslide area that occurred after being given a cantilever retaining wall was 9.4 cm. The deformation that occurred was 44.57 mm and the axial forces that occurred included a compressive force of -133.90 kN/m and a tensile force of 0.2471 kN/m. The minimum bending moment that occurred was 13.56 kN/m and the maximum bending moment was 13.04 kN/m. The minimum shear force value that occurred was 51.02 kN/m and the maximum shear force was 65.49 kN/m.
