Abstract

Indonesia, sebagai negara yang terletak di Cincin Api Pasifik menghadapi tantangan signifikan dalam pembangunan infrastruktur akibat aktivitas seismik yang tinggi, seperti jembatan LRT Kali Bekasi dan LRT Halim yang berada di wilayah dengan kondisi tanah kompleks dan resiko gempa memerlukan perencanaan pondasi yang aman. Dalam perencanaan yang telah dilakukan, daya dukung pondasi bored pile dihitung dengan menggunakan metode AASHTO, meskipun metode SNI lebih dianjurkan di Indonesia. Permasalahan utama dalam penelitian ini adalah untuk mengkaji perbandingan hasil analisis daya dukung tanah menggunakan metode AASHTO dan SNI pada pondasi bored pile di proyek pembangunan jembatan LRT Kali Bekasi dan LRT Halim. Metode yang digunakan pada penelitian mencakup pengumpulan data sekunder yang meliputi data tanah (bor log) dan data perencanaan struktur, studi literatur, analisis data tanah, analisis model struktur, serta perhitungan pembebanan jembatan LRT. Data yang diperoleh akan digunakan untuk mengevaluasi pondasi eksisting dan merancang daya dukung pondasi bored pile alternatif berdasarkan metode analitis (AASHTO dan SNI). Selain menggunakan metode analitis, simulasi PLAXIS 3D juga digunakan untuk mendapatkan hasil perencanaan pondasi bored pile yang lebih akurat. Hasil dari penelitian menunjukkan bahwa perencanaan menggunakan AAHSTO memerlukan kedalaman pile 5.5% lebih pendek dibandingkan SNI di kondisi tanah lunak (LRT Kali bekasi), dan 2% lebih pendek di kondisi tanah keras (LRT Halim). Selain itu, penggunaan PLAXIS 3D menghasilkan besar penurunan pondasi kelompok 49% lebih kecil pada tanah lunak dan 53.4% lebih kecil pada tanah keras dibandingkan menggunakan metode analitis.

Indonesia, as a country located on the Pacific Ring of Fire faces significant challenges in infrastructure development due to high seismic activity, such as the Kali Bekasi LRT and Halim LRT bridges which are located in areas with complex soil conditions and earthquake risks requiring safe foundation planning. In the planning that has been done, the bearing capacity of the bored pile foundation is calculated using the AASHTO method, although the SNI method is more recommended in Indonesia. The main problem in this research is to examine the comparison of the results of soil bearing capacity analysis using the AASHTO and SNI methods on bored pile foundations in the Kali Bekasi LRT and Halim LRT bridge construction projects. The methods used in the research include secondary data collection which includes soil data (drill logs) and structural planning data, literature study, soil data analysis, structural model analysis, and LRT bridge loading calculations. The data obtained will be used to design the bearing capacity of the bored pile foundation based on SNI, while the AASHTO method is used to evaluate the existing foundation and design the bearing capacity of alternative bored pile foundations based on analytical methods (AASHTO and SNI). In addition to using analytical methods, PLAXIS 3D simulation is also used to obtain more accurate bored pile foundation planning results. The result of the study show that planning using AASHTO required a pile depth 5.5% shorter than SNI in soft soil conditions (Kali Bekasi LRT), and 2% shorter in hard soil conditions (Halim LRT). In addition, the result of using PLAXIS 3D is 49% smaller group foundation settlement in soft soil and 53.4% in hard soil than using the analytical method.
