Evaluasi Peritungan Pondasi Bored Pile pada Konstruksi Bangunan

Abstract

Foundations are the building parts connecting the building with the soil which guarantees the building stability towards the loads as follows: own load, useful load, and outside forces to the building such as wind stress, and earthquake. A foundation must strong enough to withstand the loads from the upper structure without experiencing the decrease. The bored pile foundation support power capacity on Building Education Construction of Faculty of MIPA (Mathematics and Sciences) Physics Study Program of State University of Medan was calculated through Sondir data using the Meyerhof method (1956). The bored file on point x1y1 had 600 mm diameter by 20 m deep. The bored pile support power on x1y1 was 170.721 tons, the pile needed capacities were 3 piles, interspace bore pile was 1.5 m and interspace bored file to the edge was 0.6 m. The vertical group piles support power on point x1y1 was 446.23 tons, by the comparison of 445.58 tons > Pu = 446.23. The needed main reinforced on the bored pile was 10 D19 and stirrup reinforced used was D10 – 200. Whereas the quantities of reinforced pile sign direction of y were 51 piles by the interspace reinforced of D16 – 70.
