    Abstract

    Penelitian ini membahas penerapan metode Rigid Inclusion Full Displacement Column pada perbaikan tanah dalam proyek konstruksi Jalan Tol. Tujuan utama dari penelitian ini adalah untuk mengevaluasi efektivitas metode Full Displacement Column dalam meningkatkan daya dukung tanah dan mengurangi penurunan tanah, serta membandingkan hasil pemodelan menggunakan model material Mohr-Coulomb dan Hardening Soil. Pemodelan numeris dilakukan dengan perangkat lunak Plaxis 2D, yang mensimulasikan kondisi plane strain dan axisymmetric. Hasil penelitian menunjukkan bahwa model material Hardening Soil lebih akurat dalam memprediksi penurunan tanah dibandingkan model Mohr-Coulomb. Implementasi Full Displacement Column secara signifikan meningkatkan daya dukung dan stabilitas tanah, serta memberikan respons yang baik terhadap beban dinamis seperti gempa. Pemodelan axisymmetric juga memberikan hasil yang lebih realistis dibandingkan plane strain dalam kasus ini. Penelitian ini menggarisbawahi pentingnya pemilihan model material dan parameter tanah yang tepat untuk analisis geoteknik yang lebih akurat. Rekomendasi termasuk penggunaan model Hardening Soil untuk kondisi tanah serupa dan pentingnya melakukan analisis balik jika terdapat perbedaan dengan kondisi lapangan yang sebenarnya.

    This study discusses the application of the Rigid Inclusion Full Displacement Column method for soil improvement in a highway construction project. The main objective of this research is to evaluate the effectiveness of the Full Displacement Column method in enhancing soil bearing capacity and reducing settlement, as well as to compare modeling results using the Mohr-Coulomb and Hardening Soil material models. Numerical modeling was performed using Plaxis 2D software, simulating both plane strain and axisymmetric conditions. The results indicate that the Hardening Soil material model is more accurate in predicting soil settlement compared to the Mohr-Coulomb model. The implementation of Full Displacement Columns significantly enhances soil bearing capacity and stability and provides a good response to dynamic loads such as earthquakes. The axisymmetric modeling also yields more realistic results than plane strain in this case. This research highlights the importance of selecting appropriate material models and accurate soil parameters for more precise geotechnical analysis. Recommendations include the use of the Hardening Soil model for similar soil conditions and the necessity of performing back analysis if there are discrepancies with actual field conditions.
