Abstract

The foundation is a structural element that serves to transfer the weight of the building to the soil layer below, without the risk of sliding avalanches, or subsidence that exceeds the allowable subsidence limit. The soil is the supporting foundation of the building, or the construction material of the building itself. One of the sp. road projects. Banyan – maredan – sp. Artificial that uses one type of road pavement That is, rigid pavement in question is concrete pavement with binders in the form of Portland cement or PC that bear most of the traffic load on it. In the sp. road project. Banyan – maredan – sp. Artificial that experiences statlement or collapse caused by vehicle loads that exceed the planning limit, so that the project uses a spun pile foundation, so that in the project using a spun pile foundation measuring 30 cm in diameter as a foundation that will carry the load in the form of an on ground slab plate with a plate thickness of 30 cm. In this study, researchers will analyze the increase in the capacity of road structures in sp. Banyan – maredan – sp. Artificial using static method with Meyerhoff's formula (1956) and dynamic method with Hilley's formula (1930) obtained data from the field in the form of N-SPT data and calendar data. From these two data, the author wants to know which data has the highest supporting strength. The results of calculating the ultimate supporting strength using two methods, namely the static method with the Mayerhoff 1956 formula with SPT (Standard Penetration Test) soil data obtained supporting strength results with a minimum depth of 22 meters of Qu = 169.99 tons and at a maximum depth of 24 meters of Qu = 424.98 tons. Meanwhile, from the calculation with a dynamic method with the Hilley 1930 formula using calendring data on piles with minimum results on pole no 108 with a depth of 21 meters of Qu = 73.79 tons and on maximum pole no 98 with a depth of 23 meters of Qu = 56.54 tons. It can be seen from the two methods above from the results of SPT data obtained two types of soil which at a depth from the soil surface to a depth of 18 meters are rigid clay, silted sand, fine sand while from a depth of 19 meters to 24 meters is fine silt sand. So that the calculation of the ultimate support strength (Qu) that is more influential is the calculation of the static method with the Mayerhoff formula.
