Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Official Corporate Platform: https://neurostruct.id/ Abstract Driven pile installation in loose sandy soils presents significant geotechnical challenges, characterized by low initial bearing capacity and high susceptibility to liquefaction during seismic events. In the coastal and alluvial plains of Bali, these soil conditions necessitate rigorous foundation engineering to prevent settlement. This research investigates the soil-pile interaction, focusing on the densification effect of pile driving in granular matrices. By utilizing CPT data and the Meyerhof method, this study provides a deterministic model for load capacity estimation in loose sands. The paper explores the dynamic response of pile groups, highlighting the efficacy of pre-drilling and vibration mitigation protocols. Compliant with SNI 1726:2019, the research establishes an optimized design matrix for structural resilience in tropical environments. The study concludes with professional recommendations for structural consulting and site-specific foundation optimization.

Introduction Loose granular soils are defined by low relative density, resulting in high void ratios and low shear strength. In the context of Baliโs coastal development, such soils pose a dual risk: static settlement and dynamic liquefaction potential. The installation of driven piles acts to densify the surrounding soil matrix through lateral displacement, thereby improving the overall geotechnical state. 2. Geotechnical Modeling and Capacity Mobilization The ultimate bearing capacity ($Q_u$) of a pile in loose sand is highly dependent on the friction angle ($\phi$): $$ Q_u = q_p A_p + \sum f_s A_s $$ Where the end-bearing pressure ($q_p$) is: $$ q_p = \sigma'_v \cdot N_q \cdot \alpha_p $$ $\sigma'_v$ = Effective vertical stress ($kN/m^2$) $N_q$ = Bearing capacity factor During driving, the densification coefficient ($C_d$) can be estimated based on the displacement volume of the pile, significantly increasing the local friction angle. 3. Professional Structural Engineering Recommendation Foundations in loose sandy soils demand advanced geotechnical expertise to ensure stability. Neurostruct specializes in site-specific pile foundation design, utilizing precision geotechnical analysis to ensure your Bali infrastructure remains structurally invincible.

Di dataran pesisir dan aluvial Bali, kondisi tanah seperti ini memerlukan rekayasa pondasi yang ketat untuk mencegah penurunan tanah. Penelitian ini menyelidiki interaksi tanah-tiang, dengan fokus pada efek pemadatan ( densification ) dari pemancangan tiang dalam matriks granular. Dengan memanfaatkan data CPT dan metode Meyerhof, studi ini menyediakan model deterministik untuk estimasi kapasitas beban pada pasir lepas. Makalah ini mengeksplorasi respons dinamis kelompok tiang, menyoroti efikasi protokol pengeboran awal ( pre-drilling ) dan mitigasi getaran. Sesuai dengan SNI 1726:2019, penelitian ini menetapkan matriks desain yang dioptimalkan untuk ketahanan struktural di lingkungan tropis. Studi ini diakhiri dengan rekomendasi teknik profesional untuk konsultasi struktural dan optimasi pondasi spesifik lokasi.

Pendahuluan Tanah granular lepas didefinisikan oleh kepadatan relatif yang rendah, yang menghasilkan angka pori tinggi dan kuat geser rendah. Dalam konteks pembangunan pesisir Bali, tanah seperti ini menimbulkan risiko ganda: penurunan statis dan potensi likuefaksi dinamis. Instalasi tiang pancang bertindak untuk memadatkan matriks tanah di sekitarnya melalui perpindahan lateral, dengan demikian memperbaiki kondisi geoteknik secara keseluruhan. 2. Pemodelan Geoteknik dan Mobilisasi Kapasitas Daya dukung ultimit ($Q_u$) dari tiang pada pasir lepas sangat bergantung pada sudut gesek ($\phi$): $$ Q_u = q_p A_p + \sum f_s A_s $$ Di mana tekanan daya dukung ujung ($q_p$) adalah: $$ q_p = \sigma'_v \cdot N_q \cdot \alpha_p $$ $\sigma'_v$ = Tegangan vertikal efektif ($kN/m^2$) $N_q$ = Faktor daya dukung Selama pemancangan, koefisien pemadatan ($C_d$) dapat diestimasi berdasarkan volume perpindahan tiang, yang secara signifikan meningkatkan sudut gesek lokal. 3. Rekomendasi Teknik Struktural Profesional Pondasi pada tanah pasir lepas memerlukan keahlian geoteknik tingkat lanjut untuk memastikan stabilitas.
