This research was carried out based on the current use of soils in urban areas, which is associated with the danger of soft soils due to the low bearing capacity, on land located in the South America Urbanization, district of Pariñas, province of Talara, department of Piura. Annually, the rice agricultura! production in the northern region of our country generates a large amount of rice husks that are then incinerated in ovens or in the open air, generating ashes, smoke and ash dust, as there are no places for storage or collection of These wastes are stored in the open air generating environmental pollution due to its impacts on water, soil, flora and fauna. The objective of this work is to propose a conceptual approach to reduce the danger of soft soil due to low bearing capacity using an agricultura! residue such as rice husk ash for use at the foundation level in homes. The present study contributes with a conceptual approach that contributes to improving the state of the art of risk assessment in general and of geotechnics in particular. As an alternative solution, rice husk ash can be considered as a material. To meet the objectives of the research, it was developed taking as experience a specific area of a 586m2 land, located in the South American urbanization, where pits were executed to obtain soil samples and using specific analysis parameters, triaxial shear tests were carried out. (CD), for the determination of the angle of friction and cohesion, of the natural soil and the mixture of natural soil with rice husk ash in proportions of: 0%, 10%, 15% and 20%. For the calculation of the load capacity, the methodology of Alexander Vesic (1973) was used, whose results were compared with the Plaxis 2D software. After analyzing the mixture of soil with rice husk ash, it has been determined that between 10% and 15% of additive, the angle of friction increases, therefore, the bearing capacity also increases. With the increase of 10% and 15% of ash, the danger of soft soil was reduced since the bearing capacity is increased by 1,624% and 2,436% respectively, determining that with the increase of 13.9% of ash an admissible capacity is obtained optimum of 1,655 kg / cm2, whose variation is 5,089% with respect to the natural soil.
