Abstract
Bandara Soekarno-Hatta, yang berlokasi di Cengkareng, Tangerang Banten yang masuk dalam Proyek Connection NP1-Secondary Apron. Bandara ini mempunyai kondisi tanah yang sifat atau karakteristik tanah medium soft clay, untuk mengatasi penurunan pada kondisi tanah medium soft clay, diperlukan perbaikan tanah, kalau tidak dikhawatirkan akan terjadi kegagalan dalam perkerasan landasan sisi udara (taxiway). Perbaikan tanah ini menggunakan metode Injection Pile.
Tahapan metode Injection Pile diawali mengumpulkan data tanah dan parameter tanah. Menghitung daya dukung tiang tunggal pada kondisi tanah, yang ada secara manual sesuai dengan metode hitungan yang digunakan. Tiang tunggal dan tiang kelompok dimodelkan pada Plaxis 2D V.8.6 dan Plaxis 2D V.2015. Pemodelan tiang tunggal dimodelkan pada model tanah axisymmetry sedangkan pemodelan tiang kelompok dimodelkan pada model tanah plane strain.
Hasil perhitungan daya dukung tiang tunggal pada N-SPT 60 kedalaman 28m mendapatkan nilai Qs sebesar 226.08 kN, nilai Qp sebesar 7912.80 kN dan nilai Qu sebesar 8138.95 kN. Kapasitas maksimum untuk tiang tunggal pada pemodelan Plaxis 2D adalah sebesar 124.5 kN/m2. Penurunan tanah yang terjadi dari hasil pemodelan pada Plaxis 2D untuk tanpa stabilisasi menunjukkan persentase sebesar 6,74% penurunan lebih besar daripada menggunakan stabilisasi tanah (Injection Pile) sebesar 3,26%. Injection Pile dapat diterapkan untuk meningkatkan daya dukung tanah serta mengatasi masalah penurunan sesuai yang disyaratkan.

Soekarno-Hatta Airport, is located in Cengkareng, Tangerang Banten which is included in Connection NP1-Secondary Apron Project. This airport has a soft clay medium soil condition with soft characteristic, to overcome the decrease in soil condition of soft clay medium, soil repair is needed, otherwise there will be a failure in the pavement of the taxiway. This soil improvement uses the Injection Pile method.
Stages of Injection Pile method begins by collect soil data and soil parameters. Calculates the carrying capacity of a single pole on soil conditions, which exists manually according to the calculation method used. Single pole and group poles are modeled on Plaxis 2D V.8.6 and Plaxis 2D V.2015. Single pole modeling is modeled on axisymmetry soil model while modeling of group pole is modeled on plane strain ground model.
The result calculation of single pole bearing capacity on N-SPT 60 28m depth get the value of Qs equal to 226.08 kN, value of Qp equal to 7912.80 kN and Qu value equal to 8138.95 kN. Maximum capacity for single pole on Plaxis 2D modeling is 124.5 kN / m2. The decrease of soil occurring from the modeling results in Plaxis 2D for non-stabilization showed a 6.74% percentage decrease greater than using an earth stability (Injection Pile) of 3.26%. Injection Pile can be applied to increase the carrying capacity of the soil and to overcome the problem of decline as required.
