In large cities, urban growth has become increasingly vertical due to geographic limitations and population saturation. This has led to an increasing demand for basements in high-rise buildings in places like Lima. However, deep excavations present challenges when structures that cannot be removed or similar constraints are encountered. The objective of this thesis was to evaluate the performance of micropiles as horizontal support systems in conjunction with the umbrella method in a project that also incorporates piles and anchored walls, specifically in sandy soils in Lima. Plaxis 2D software and the Finite Element Method were used. The process began with the collection of field data on soil, water table, moisture, loads and materials. Then, the structure was modeled in Plaxis 2D with this data and the results were analyzed. The micropiles demonstrated a maximum vertical settlement of 1.57 mm and a maximum horizontal displacement of 2.59 mm, within Peruvian regulatory limits. These results support the efficiency of micropiles as a solution for construction in restricted areas. This thesis contributes to the knowledge on horizontal support in dense urban areas with geographical limitations, being a valuable reference for future similar projects. In summary, it is concluded that micropiles, together with other shoring techniques, are effective in addressing the challenges of construction in increasingly vertical urban environments, ensuring the safety and stability of buildings.
