Analysis of a two pile frame for a horizontal force

Abstract

The article analyzes a pile frame composed of two bored piles with a diameter of 40 cm. The frame is subjected to a horizontal force. Calculations in three different method are conducted – subgrade reaction approach, 2D plaxis and 3D plaxis, after which a comparison was made between the results of the individual methods. The aim is to see under what conditions a subgrade reaction method is suitable for use without moving away from sure side. Results were also obtained for the distribution of the value of the spring constant by depth, as well as values for the ratio between the resistance of the second and first pile. A proposal has been made for obtaining a p-curve that can be applied to any of the linear approximation methods.
