Currently, the amount of suitable land available for civil engineering is limited. Due to urban and population development in the face of natural disasters, it is necessary to resort to soil improvement systems where deformations and settlements are controlled. The objective of this work is to analyze the design of micropiles used in the foundation for perimeter fences of the I.E. 88023 Almirante Miguel Grau in Chimbote through the calculation of tensile load tests in order to find the relationship factor between the real installed tensile capacity and the theoretical admissible tensile capacity of the micropile. The initial design was analyzed before the liquefiable soil under study, which has a dimension of 5 m deep, 150 mm in diameter, capacity per shaft of 11.1 Ton, load capacity per tip equal to 1.7 Ton and a load capacity of 12.8 Ton. Likewise, traction tests were carried out that showed a real ultimate capacity of 6 Tons, validating the construction process and ensuring the capacity to withstand the loads foreseen in the theoretical calculation, which was 3 Tons. In addition, the ultimate real and theoretical geotechnical design capacities were compared, obtaining a resizing factor of 2. This factor is additional data during the design itself that allows the micropile to be optimized in terms of length and diameter. Therefore, the micropile was redesigned with a depth of 4.15 m and a diameter of 125 mm, with a load capacity per shaft of 5.3 tons and a load capacity per tip of 0.8 tons, reaching a total load capacity of 6.1 tons. Finally, the analysis of the micropile design through load tests on low-resistance soils with potentially liquefiable sand strata of this research is validated by the resizing factor, which results in a reduction in costs, labor and improves the project performance, maintaining adequate load capacity.
