Abstract

A foundation is a part of an engineering system that works by transmitting the load it supports and its own weight into the soil or rock beneath it. In this research, the author plans to compare the bored pile foundation that has been applied to the building with other alternative foundations, namely pile foundation 1 with a depth of 38 meters with a diameter of 0.8 meters, and pile 2 with a depth of 38 meters with a diameter of 1 meter in terms of bearing capacity and the magnitude of the decline that occurred. Then the foundation bearing capacity was calculated using the Meyerhof (1976), McClelland (1974), Skempton (1966), and Reese & O'neill (1999). Single pole reduction using the Vesic (1977) and Poulos & Davis (1980) methods and using the Plaxis v.20 program. Furthermore, the results of the calculations compared the bored pile foundation with pile models 1 and 2. It was found that the bored pile foundation and pile foundation 1 did not meet the permit limit for foundation settlement, only pile foundation 2 met the limit, namely a decrease of less than 10% of the foundation diameter.

Abstract

The method of driving new piles in existing buildings using existing piles is often used to speed up the construction period. The load distribution and displacement of the new pile need to be investigated further because of the influence of the existing pile. The lateral load displacement method (p-y curve) is used to analyze the load and displacement of the pile using threedimensional finite element analysis. The new and existing piles used are piles with a diameter of 0.6 meters, a thickness of 0.1 meters, a pile depth of 17 meters, and the distance between the new piles and the existing piles is 1 meter. The horizontal load applied is 150 kN on the pile head which is 1 meter from the ground surface. This research was carried out on clay with the Modified Cam Clay constitutive model. The results of three-dimensional finite element analysis show that the horizontal resistance of the new pile increases at the pile head due to the presence of the existing pile.
