In the present study, the performance of micro-piles for the improvement of loose sandy soils under dynamic loading on strip foundations was investigated. For this purpose, finite element numerical method (FEM) by Plaxis3D software has been used to implement loading conditions and evaluate deformations in loose sandy soils below the strip. The modeling process includes geometrical, behavioral models, boundary condition, material properties and dynamic modeling which that implemented on both unreinforced and reinforced strip foundation by micro-pile. Based on the results of the study, it can be well stated that the implementation of micro-piles has been able to improve loose sandy soils in strip foundations under dynamic loading conditions. So, the use of micro-communities in improving soil conditions against similar soils can be suggested.
