Estimación del esfuerzo de adherencia hormigón-suelo mediante el ensayo de corte directo y el uso del dinamómetro, aplicado en la base de muros y anclajes tipo clavo

Abstract

In civil engineering, to perform a good design of retaining walls and nail anchors, it is necessary to know the basic parameters of the soil such as friction angle, cohesion, specific weight, to determine the behavior of the soil at the base of the wall, the soil retained behind the wall, also in the contour of the bulb in nail anchors, in order to determine the adhesion stress between the concrete and the soil. This research presents an alternative analysis using the modified direct shear test, in which a laboratory simulation of the shear strength conditions between a concrete wall in contact with the soil is carried out, in the same way nail anchors were built on a reduced scale, in different types of soil and heights, in this way it will be possible to estimate the adhesion between the concrete bulb and the soil, in order to carry out economical and technically feasible retaining works.
