The occurrence of the "Child Phenomenon", in 2017, caused a series of disasters in various basins located west of the city of Lima, which event constituted the beginning of the search for information, finding within it the Study "Scenarios of disaster risks – Huachipa Sector ”Lurigancho Chosica-Lima Metropolitan District” developed by INDECI in agreement with UNDP and CESAL. In consideration of this study, as regards the urban settlement and consolidation of the right bank of the Huaycoloro stream, the adjacent area occupied by the PETRAMAS and UNICON companies has been assumed as the area of the present investigation; being relevant the existence of a large amount of fluvial material as a result of cleaning the channel of said stream; likewise, some amount of colluvial debris of granodioritic rock on the Cajamarquilla slopes. The aforementioned finding has allowed to orient the direction of the research towards the design of support walls with mechanically stabilized soil MSE, which responds to the requirement of optimization of urban planning in this area, in correlation to an adequate and abundant existence of granular soil. The best way to take advantage of the granulometric variety of the soils of the Huaycoloro stream and the Cajamarquilla slope is through the use of various types of reinforcement, which implies the achievement of a structural efficiency applicable to various requests of geomorphology, height of the element and the type of granulometry of the soil compatible with each reinforcement, considering for this purpose the use of geosynthetics (geotextiles and geogrids) and gabions. Under this mandate, all structural design of MSE walls requires the verification of external stability, overturning, sliding and load capacity; which is applicable in a simple way when using gabions as reinforcement; However, when the reinforcement is with geosynthetics, the internal stability verification must be previously performed, which correlates the physical properties of said reinforcements and the soil. However, due to various circumstances that converge in all research, the use of the values of the soil parameters to be used as a structural element of the MSE walls (ϒ1, ɸ'1 and c'1,) lead to epistemic uncertainty from the point of view of geotechnical view, which, in the present investigation, has generated a probabilistic analysis and elucidation of the reliability of use of these parameters. This, in correlation to the series of factors that intervene in the designs and in the discretion of the designer or researcher, will result in a product (MSE wall) with structural efficiency. The term "structural efficiency" should be understood as "the ability to achieve a structure with the minimum of resources, and at the lowest possible cost and time", which is based on a series of experiences that can be synthesized as: the optimization of processes for maximize (profits, speed, quality, etc.), or minimize: (costs, time, risks, error, etc.), all of which will imply sharpness in the decision-making of the designer, as well as the executor of the work.
