Abstract

[ID] Perkerasan Sistem Pelat Terpaku merupakan pengembangan Sistem Cakar Ayam yang berfungsi sebagai salah satu alternatif solusi untuk mengatasi permasalahan konstruksi jalan pada tanah lunak. Selain itu, kenaikan kapasitas dukung tanah dasar akibat pengaruh dukungan tiang-tiang pada pelat akan mengurangi kebutuhan tebal perkerasan beton dan memperkaku sistem perkerasan. Penelitian ini bertujuan untuk mempelajari pengaruh diameter tiang masif dan faktor aman terhadap lendutan pelat terpaku tiang tunggal. Dimensi struktur pelat terpaku dan data material mengacu pada Puri (2017). Sistem ini dibebani dengan pembebanan tekan sentris. Perhitungan lendutan dan gaya dalam pelat menggunakan metode BoEF, berdasarkan tambahan modulus reaksi tanah dasar ekivalen yang dibandingkan dengan lendutan hasil pengamatan. Hasil analisis menunjukkan bahwa besaran faktor aman mempengaruhi nilai lendutan hitungan. Lendutan hitungan meningkat dengan peningkatan faktor aman. Penggunaan faktor aman 1,0 memiliki pola lendutan mendekati lendutan pengamatan untuk tiang bulat. Analisis perhitungan lendutan dengan ukuran mini pile  yang semakin besar menghasilkan lendutan pelat yang semakin kecil. Variasi SF tidak berpengaruh signifikan terhadap momen pelat.

[EN] The Nailed-Slab Pavement System is the development from the pavement of the Cakar Ayam System which as an alternative solution to solve the problem of road construction in soft soil. In addition, the increase in bearing capacity of the subgrade due to the influence of the poles support on the plate will reduce the need for thick concrete pavement and strengthen the pavement system. This study aims to learn the effect of massive pole diameter and safe factors on the deflection of single-pile Nailed Slab. The dimensions of the Nailed-slab structure and material refer to Puri (2017). This system is burdened with press centric loading. Calculation of deflection and force in plates uses the BoEF method, based on the additional modulus of the subgrade equivalent reaction which is compared to the deflection observed. The results of the analysis show that the magnitude of the safe factor affects the value of the deflection calcutation. This deflection  increases with an increase in safe factors. The use of the safe factor 1.0 has a deflection pattern that is closer to the observation deflection for the round pile. Analysis of the deflection calculation with the size of the mini pile which gets bigger results in a smaller slab deflection. SF variations have no significant effect on the plate moment.
