Estudio patológico en los muros de contención de la vía Bogotá- Villeta entre los Km 51+010 y Km 51+ 119

Abstract

Functional structures have served for the development of humanity since the Middle Ages, a time when the creation of elements and structures that facilitated work and the connection of civilizations began. The present work is developed in one of the main road structures of Colombia; the Vía Bogotá-Villeta, in which it was inaugurated after the construction of retaining walls on the sides of the road in 2016. A year later, module 2 of Km 51+010 and Km 51+119 begins to present injuries to the wall and the pavement structure that have advanced to the point of compromising the integrity of the patient and users.

It is for the above that the present work is carried out as a pathological study from a quantitative research approach, that is, it is based on a sequential study, initially composed of a research framework, which is supported by the collection of information from the patient, hypotheses of the causes that affect the patient, construction and detail of the patient's clinical history and finally the results obtained from the development of laboratory tests.

On the other hand, with the descriptive investigation, it is exposed that the patient presents pathologies such as displacement of the containment screens and therefore of the road network, which has led to the occurrence and presence of other injuries such as landslides, subsidence and cracks in the modules of the wall and the track; It is for these analyzes that two failure hypotheses are proposed, one of these is the resistance capacity of the concrete and the other corresponds to settlements derived from overloads in the pavement structure that supports the Retaining Wall. Consecutively and According to the information obtained from the laboratory tests, it is concluded that the resistance of the concrete is approximately 40 MPa, which ensures that this item is not the trigger for the Wall's pathologies. Once such an approach was ruled out, the second stage of the pathological study was developed, which consists of the approach to the diagnosis of the cause of the lesions and also the realization of intervention proposals to solve them, as well as the recommendations and conclusions of the case study.

According to this investigation, the wall currently meets the initial design objective, which is to contain the land on which the road network was built, it is also concluded that the structure does not present relevant risks of collapse, however, a comprehensive intervention must be carried out with in order to correct and mitigate the origin of new injuries that affect the stability and integrity of the retaining wall.
