STUDI PERENCANAAN PONDASI TIANG PANCANG PADA JEMBATAN KERETA API KM 95+870 JOMBANG MADIUN

Abstract

ABSTRACTBridges are complementary buildings that are used to continue the road or railroad that are cut off due to obstacles such as rivers, waterways, roads and valleys. As with the Jombang - Madiun railway bridge BH 258 km 95 + 870 Kertosono. The bridge that was built on the Brantas river aims to increase the number of new lanes to four lanes.The author wants to plan the development with a pile foundation. This foundation is planned by the Mayerhof method based on the SPT data obtained from the Contractor on the construction of the project namely Hutama, Modern Mitra, KSO.In the study of pile foundation planning obtained a vertical load of 8,708,531 tons, horizontal load of 567.69 tons, bearing capacity of the foundations was equal to 10.006.22 tons greater than the axial force that occurred which was 8,708,531 tons. The rolling stability value is 16.04 greater than 1.5 and the stability of the displacement is 4.46 more than 1.5, the stability of the decrease is 22.34 tons / m2 > the carrying capacity of the soil is 12.2 tons / m2 (not okay) then the pile is needed to hold vertical style.Keywords: Bridge, Mayerhof, Pile
