Abstract

In the construction of public works infrastructure, especially road infrastructure works, bridge construction work plays a very important role besides the construction of the road itself. One of the things that deserves the attention of the planners in designing a bridge structure is the design of the substructure, this is because the substructure determines the quality and service life of a bridge. In addition, at present many cases of bridge structure failures are caused by failures of the substructure in holding the load acting on the bridge. The aim of this study was to determine the stability of the abutment to sliding failure and the stability of the abutment to overturning failure on the construction of the Aifa bridge in the Bintuni Bay Regency. From the results of the calculation of the stability of the abutments to sliding failure, when the abutments are in normal conditions was obtained safety factor (SF) values 1,907, in condition of the upper structure load is not working was obtained safety factor (SF) values 1,045 and during earthquake conditions was obtained safety factor (SF) values 1,419. While the results of the calculation of the stability of the abutments to overturning failure, when the abutments are in normal conditions was obtained safety factor (SF) values 4,640, in condition of the the upper structure load is not working was obtained safety factor (SF) values 1,658 and during earthquake conditions was obtained safety factor (SF) values 3,159. Because obtained safety factor (SF) values greater than 1, so that the stability of the abutment is safe to sliding failure and overturning failure.
