Abstract
Selection of the type of support foundation should be taken accurately because the strength of the foundation as a support for the upper structure greatly influences the strength of building. Wherefore, analysis of foundation carrying capacity and settlement are indispensable. This research aims to determine support capacity by applying various methods and the value of settlement that occurs due to loading from upper structures.This research utilizes method, such as Skempton Method, Cooke dan Whitaker Method, Meyerhoff Method, Alpha Method, Lambdha Method and Betha Method. Its also employes Finite Element Method, namely Software Plaxis 2D V.8.6 as calculation and modelling tools, final results of the analysis could be compared with empirical and non-empirical methods. The object of this is Lemah Abang Bridge that located in Sleman Regency and Gunungkidul Regency frontier, Yogyakarta Province, with Well Foundation or Caisson foundation as the lower structure. The results show that the support capacity meets the requirements, such as : Skempton Method is 1693,701 kN; Cooke dan Whitaker Method 2695,063 kN; Meyerhoff Method is 2695,063 kN; Alpha Method is 632,374 kN; Lambdha Method is 1663,359 kN; Betha Method is 1579,751 kN and field data is sebesar 20570,876 kN. According to the research, the minimum value of Qu are obtained by using Meyerhoff Method and Betha Method. Furthermore, The value of settlement with empirical method is 2,5075 cm and the settlement with Software Plaxis 2D is 4,62 cm. Based on the results, further analysis are needed by using another empirical methods or other softwares, to get various results.
