Investigating the effect of dimensions and distance of micro piles on the bearing capacity in a foundation settlement in gravel soils

Abstract

The piles are members of steel, concrete, reinforced concrete and wood, which is used to build a deep pile, if the landing capacity is not suitable for use. In spite of high costs, there are many cases in which there are numerous cases of pile sticks used to protect the building against sewage and other factors. The load on the pile is tolerated in two ways by the pile, part of which is tolerated by the side-pile resistance and the other part by the reciprocating tip of the pile. This composite system is called a piled raft system, or a piled raft foundation. In this research, Plaxis finite element software has been used to investigate the capacity of microfractory bearing. The results of this modeling show that the maximum displacement is about 3 mm, which occurred at the final modeling stage. In the first stage, the modeling of the level of displacement is very small, due to the grain size of the soil and the dry assumption of the material. In the second stage, the spatial variations show a sudden increase, due to the presence of pile s and the weight of the pile holder. In the third stage, the soil is completely compressed so that the forces have no significant effect on the summation, and the rate of the second stage and the third settlement are not significantly different
