| Abstract: | Pondasi merupakan elemen struktural yang berfungsi menyalurkan beban bangunan ke tanah pendukung secara aman. Pada proyek pembangunan gedung showroom dan kantor di Kota Medan, digunakan pondasi dalam berupa tiang spun pile untuk mengakomodasi beban struktur dan kondisi tanah yang bervariasi. Penelitian ini bertujuan menganalisis daya dukung pondasi spun pile berdasarkan data Cone Penetration Test (CPT) melalui pendekatan perhitungan analitik empiris. Kajian teori meliputi konsep daya dukung tanah, karakteristik tanah, metode Aoki–De Alencar untuk tiang tunggal, metode Converse–Labarre untuk tiang kelompok, serta pemodelan numerik menggunakan Plaxis 2D. Metode penelitian bersifat kuantitatif dengan pengumpulan data primer berupa CPT dan Pile Driving Analyzer (PDA) Test, serta data sekunder dari laporan proyek dan literatur. Hasil analisis menunjukkan bahwa daya dukung tiang tunggal berdasarkan metode Aoki–De Alencar sebesar 381,4 ton, hasil pemodelan Plaxis 2D sebesar 288,4 ton, dan hasil PDA Test sebesar 306,5 ton, sedangkan daya dukung pondasi kelompok menggunakan metode Converse–Labarre diperoleh sebesar 12996,135 kN. Sehingga kapasitas dukung pondasi lebih besar dibandingkan beban kerja, yaitu 12996,135 kN > 7627,23 kN, yang menunjukkan bahwa pondasi berada dalam kondisi aman. Perbandingan hasil menunjukkan bahwa nilai PDA Test lebih kecil 19,64% dibandingkan metode Aoki–De Alencar, sedangkan hasil Plaxis 2D lebih kecil 5,91% terhadap PDA Test dan 24,38% terhadap metode Aoki–De Alencar. Penelitian ini menyimpulkan bahwa kombinasi metode analitik, pemodelan numerik, dan pengujian lapangan memberikan hasil analisis daya dukung pondasi spun pile yang lebih akurat dan andal. Foundations are structural elements that function to safely transfer building loads to the supporting soil. In the construction project of a showroom and office building in Medan City, deep foundations in the form of spun pile piles were employed to accommodate structural loads and varying soil conditions. This study aims to analyze the bearing capacity of spun pile foundations based on Cone Penetration Test (CPT) data using empirical calculation approaches and finite element modeling. The theoretical framework includes soil bearing capacity concepts, soil characteristics, the Aoki–De Alencar method for single piles, the Converse–Labarre method for pile groups, and numerical modeling using Plaxis 2D. The research adopts a quantitative approach with primary data obtained from CPT and Pile Driving Analyzer (PDA) tests, as well as secondary data from project reports and relevant literature. The analysis results indicate that the single pile bearing capacity obtained using the Aoki–De Alencar method is 381.4 tons, the Plaxis 2D modeling result is 288.4 tons, and the PDA test result is 306.5 tons, while the pile group bearing capacity is 12,996.135 kN. (12,996.135 kN > 7,627.23 kN), confirming that the foundation is in a safe condition. Comparative analysis shows that the PDA test result is 19.64% lower than the Aoki–De Alencar method, whereas the Plaxis 2D result is 5.91% lower than the PDA test and 24.38% lower than the Aoki–De Alencar method. This study concludes that combining empirical methods, numerical modeling, and field testing provides a more accurate and reliable analysis of spun pile foundation bearing capacity. |
