Analisa Penurunan Raft-Piled Foundationarea Bogie Warehouse Proyek Jakarta LRT Section Depot

Abstract

<span><em>The foundation of the raft post is the bottom structure of a building that channeled the load from the structure </em><span><em>over the soil under it. Carrying capacity of drill pile foundation is influenced by the capacity of the pole tip</em><br /><span><em>and bearing capacity of the pole blanket. The decline in this area can be an immediate decline and a </em><span><em>decrease in consolidation. This study aims to analyze the decrease of raft poles and the proportion of load </em><span><em>bearing in the bogie area of the Kelapa Gading LRT warehouse depot - Jakarta. From the analysis of the</em><br /><span><em>NSPT test results in the field, the ultimate carrying capacity and the decrease that occurred on the raft poles </em><span><em>were obtained. Based on the results of calculation of the ultimate carrying capacity of a single drill pole of </em><span><em>1.1 x 104 kN and the carrying capacity of the group is 1.1 x 108 kN. Calculation of group efficiency with the </em><span><em>Feld method is obtained at a value of 0.588. In the calculation of the immediate decline of the pole, a value of </em><span><em>5 cm is obtained and a decrease in consolidation of 7 cm. From the calculation of the proportion of raft pole</em><br /><span><em>load bearing the value of Pr = 6 x 10-6 is obtained, which means that load bearing can be said to be </em><span><em>dominated by rafts.</em></span></span></span></span></span></span></span></span></span></span></span><br /><br class="Apple-interchange-newline" /></span>

Analisis Kebutuhan Kapasitas Fondasi Piled Raft Studi Kasus Pegadaian Tower, Jakarta Pusat

“…Fondasi piled raft ini dipilih karena dapat mengendalikan penurunan, kestabilan, dan daya dukung tanah dengan baik [2] [11]. Fondasi raft digunakan untuk mendistribusikan beban bangunan secara merata karena bangunan tersebut termasuk bangunan bertingkat tinggi dan memiliki beban yang sangat besar.…”
