Abstract: Micropile technology is a reliable pile system that can withstand large capacity axial or lateral loads with minimal disturbance to the existing structures.

Use of micropile (mini pile, reticulated pile, etc.) started in early 1950s in Italy for underpinning applications of historic buildings damaged during World War II. Micropile technology is a reliable pile system that can withstand large capacity axial or lateral loads with minimal disturbance to the existing structures. They became very popular due to their ability to transfer loads efficiently through skin friction and due to their many installation advantages over conventional pile systems. Micropile is “drilled and grouted pile” with steel pipes which diameters is less than 300mm and driven by boring machine, featuring small diameter with thick wall and mechanical joints with couplers not welding. The advantages of this system are practicable with small space, cost effective and less construction noise and vibration. In this study soil slope is modelled in Abaqus 3D and some parameters such as number of piles, degree, diameter and position of the micropiles has been studied.
