Analisa Perhitungan Daya Dukung Pondasi Tiang Pancang Overpass Sei Semayang STA. 0+350 pada Proyek Pembangunan Jalan Tol Medan-Binjai

Abstract

Civil building such as buildings, bridges, highways, tunnels, tower sand embankments must have a foundation that can carry its load. The floor or ground work basically do not have a sufficient carrying capacity to carry the load or its soil depths deep enough to reach the ground are allowed to support the construction there on, it is usually used stake. To determine the carrying capacity of the mast were met or not, can use Meyerhoff’s method with SPT data and PDA test, then the calculation can be forwarded on to calculate the efficiency of the stake. This efficiency calculation formula used Converse- Labarre’s method because it ground support on the object is sand ones. From the analysis and calculation of pile bearing capacity with SPT results based Meyerhoff’s metode the first Abutment has a carrying capacity of 767.88 tons of single pile, pile bearing capacity of 12649.45 tonnes groups and the second Abutment has a single pile bearing capacity of 732.5 tons, carrying capacity pole group amounted to 12056.755 tons. Each carrying capacity in both experiments have reached a hard soil as deep as 21 meters but the analysis and calculation of pile bearing capacity with PDA Test has 394,9 tons of the OP 1 and 325,9 tons of OP 2.
