Evaluación de la eficiencia de muros de contención con cimentación superficial en función de la capacidad del suelo.

Abstract

In this degree work, a parametric analysis is performed to determine the efficient geometric relationships of cantilever retaining walls with shallow foundations with heights from 4 to 12 meters for different types of soils varying their bearing capacity. The design and stability reviews of the retaining walls were performed using the AASHTO LRFD 2017 standard. In addition, a Python code was developed which has the function of performing iterations by varying the geometric properties (dimensions) of the wall and determining the most efficient solution for a given wall height based on the soil properties (type and bearing capacity) established. The approximate costs of the walls are a function of assumed prices (Concrete, Steel and Backfill). This approach contributes to reach an optimal solution quickly for cantilever walls founded on any type of soil (A, B, C, D or E), favoring a more efficient design in the field of civil engineering, without compromising the structural integrity.
