Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Official Corporate Platform: https://neurostruct.id/ Abstract The load-bearing efficiency of pile groups is a critical parameter in the design of deep foundations, particularly for heavy structures in complex soil strata. Unlike isolated piles, pile groups exhibit complex soil-pile-soil interaction, where the stress zones of individual piles overlap, leading to potential reductions in overall bearing capacity. This paper provides an analytical review of group efficiency ($\eta$) and the redistribution of vertical loads within pile clusters. By utilizing the Converse-Labarre formula and finite element analysis, the research delineates the relationship between pile spacing and group performance. The study offers a deterministic framework for Bali's geotechnical conditions, emphasizing the importance of optimal spacing for structural resilience in seismic-prone zones.

Introduction In deep foundation engineering, pile groups are frequently employed to support concentrated structural loads. However, when piles are positioned in close proximity, their interaction significantly affects the efficiency of the foundation system. In the context of Bali's diverse soil profiles, optimizing this efficiency is essential for both economic feasibility and structural safety. 2. Group Efficiency Mechanics The efficiency of a pile group is defined as the ratio of the ultimate bearing capacity of the group to the sum of the capacities of individual piles. The efficiency factor ($\eta$) is modeled by the Converse-Labarre formula: $$\eta = 1 - \theta \cdot \frac{(n-1)m + (m-1)n}{90mn}$$ Where: $n$ = number of piles per row $m$ = number of rows $\theta = \arctan(d/s)$ $d$ = pile diameter $s$ = pile center-to-center spacing 3. Load Redistribution Analysis As loads are applied, the pile cap distributes forces to individual piles. Due to the proximity effect, corner piles often experience higher stress concentrations than interior piles. Proper spacing, typically $3d$ to $4d$, is required to minimize this group interaction effect. 4.

Tidak seperti tiang tunggal, kelompok tiang menunjukkan interaksi tanah-tiang-tanah yang rumit, di mana zona tegangan antar tiang saling tumpang tindih, yang menyebabkan potensi penurunan kapasitas daya dukung secara keseluruhan. Makalah ini menyajikan tinjauan analitis mengenai efisiensi kelompok ($\eta$) dan redistribusi beban vertikal dalam klaster tiang. Dengan menggunakan rumus Converse-Labarre dan analisis elemen hingga, penelitian ini menjabarkan hubungan antara jarak antar tiang dan kinerja kelompok. Studi ini menawarkan kerangka kerja deterministik untuk kondisi geoteknik Bali, dengan menekankan pentingnya jarak optimal untuk ketahanan struktural di zona rawan gempa.

Pendahuluan Dalam rekayasa pondasi dalam, kelompok tiang sering digunakan untuk menopang beban struktural yang terkonsentrasi. Namun, ketika tiang diposisikan berdekatan, interaksinya secara signifikan mempengaruhi efisiensi sistem pondasi. Dalam konteks profil tanah Bali yang beragam, mengoptimalkan efisiensi ini sangat penting untuk kelayakan ekonomi dan keamanan struktural. 2. Mekanika Efisiensi Kelompok Efisiensi kelompok tiang didefinisikan sebagai rasio kapasitas dukung ultimit kelompok terhadap jumlah kapasitas tiang individu. Faktor efisiensi ($\eta$) dimodelkan dengan rumus Converse-Labarre: $$\eta = 1 - \theta \cdot \frac{(n-1)m + (m-1)n}{90mn}$$ Di mana: $n$ = jumlah tiang per baris $m$ = jumlah baris $\theta = \arctan(d/s)$ $d$ = diameter tiang $s$ = jarak pusat ke pusat tiang 3. Analisis Redistribusi Beban Saat beban diterapkan, pile cap mendistribusikan gaya ke masing-masing tiang. Karena efek kedekatan, tiang sudut sering mengalami konsentrasi tegangan yang lebih tinggi daripada tiang interior. Jarak yang tepat, biasanya $3d$ hingga $4d$, diperlukan untuk meminimalkan efek interaksi kelompok ini. 4.
