This work aims to solve the problem of the effects of seismic waves on soft soils with an improved surface layer in the department of Cajamarca, which, given its geomechanical characteristics, is prone to suffer settlement effects and surface deformations if transmission of energy. from the focus to the ground surface. The design of the proposal consists of analyzing the way in which the improved soil stratum affects the propagation of waves, which will be indicated by a computational analysis with which the values of the period, amplification and maximum acceleration of the soil will be evaluated from an accelerogram by modeling in the Deepsoil spectral fitting software. For this, an improved foundation design has been considered with piles of compacted aggregate spaced at 1.90m and 3.50m from the foundation depth, on which a square plate e=1m will sit. This alternative solution allowed an increase in the rigidity of the soil. . Furthermore, by applying an earthquake with a maximum acceleration of 0.08g, the result of accelerations of 0.37g and 0.30g has been obtained for soft soil and improved soil respectively; also, a reduction in the S wave amplification values of 1.80 and 1.40. Likewise, the response spectrum of the site has been obtained and it has been compared with the seismic amplification factor C of the E.030 standard in which the results show a C=2.14 lower than the C=2.5 proposed in the E.030 earthquake resistant standard. Finally, the amplification of the waves in improved soil is reduced by 22% compared to unimproved soil, and the result shows that soft soil presents a peak amplification in areas of 0.7s. The softer the soil, the greater the effects of the earthquake will be, while by stiffening the soft layer the damage to the structures is reduced by 40% and the settlement by 44%.
