Abstract
La presente investigación se desarrolló en la carretera Tarapoto – Yurimaguas, Km 19+950 – Km 19+990 de la provincia y departamento de San Martín, con el propósito de realizar un diseño de Barreras Dinámicas y su relación para la protección ante la caída de rocas, prevenir accidentes y pérdidas de vidas
humanas así como proteger la vía que es una de las más afectadas por las constantes caídas de rocas registradas en épocas de lluvias (Octubre-Abril), además es el medio de transporte terrestre único para la conexión entre la cuidad de Tarapoto y el distrito de Yurimaguas.
El propósito de implementar barreras dinámicas en la carretera Tarapoto –
Yurimaguas en el km 19+950 – Km 19+990, es para mitigar los efectos
destructivos de las rocas que actualmente presentan daños considerables al tramo en estudio y permitir que los pobladores hagan uso de esta vía sin temor a encontrarse en peligro al transitarla.
Las pantallas dinámicas son estructuras metálicas flexibles cuyo objetivo es detener rocas o material desprendido de un talud, evitando que llegue a una zona
concreta a proteger, como pueden ser poblaciones, vías férreas o carreteras.
Estas estructuras son muy demandadas por su bajo coste y facilidad de instalación, y son capaces de proteger de impactos de muy amplio espectro en cuanto a energía se refiere. En este trabajo el objetivo es la optimización de material en cada componente por lo que la energía absorbida por unidad de masa
es la variable principal a tener en cuenta.
Para el desarrollo de la investigación fue necesario conocer las propiedades
físicas y mecánicas de las rocas para determinar el ángulo de fricción, lo cual
nos ayudó a determinar el valor límite de resistencia al deslizamiento.
Se investigó un total de 40 metros lineales con el objetivo de diseñar barreras
dinámicas, las mismas que fueron diseñadas para lograr la capacidad óptima de
retención de las rocas.

Se ha concluido que las barreras dinámicas cumplen con su eficacia al disminuir
el impacto del flujo de rocas que afecta a la población, esta evaluación es de fácil
y concreto desarrollo para cualquier evaluador. Asimismo, recomienda que el
estudio pueda afinarse en el futuro con la validación de más proyectos de
investigación que facilitan la instalación y mejoran el funcionamiento donde
necesitan ser colocados las barreras dinámicas.
This research was developed on the Tarapoto - Yurimaguas highway, Km 19 + 950 - Km 19 + 990 of the province and department of San Martín, with the purpose of carrying out a design of Dynamic Barriers and their relationship for the protection against the fall of rocks, prevent accidents and loss of human life as well as protect the road that is one of the most affected by the constant falls of rocks registered in the rainy season (October-April), it is also the only means of land transport for the connection between the city of Tarapoto and the district of Yurimaguas. The purpose of implementing dynamic barriers on the Tarapoto - Yurimaguas highway at km 19 + 950 - Km 19 + 990, is to mitigate the destructive effects of the rocks that currently present considerable damage to the section under study and allow the residents to make use of this road without fear of being in danger when traveling. Dynamic screens are flexible metal structures whose objective is to stop rocks or material detached from a slope, preventing it from reaching a specific area to be protected, such as towns, railways or roads. These structures are in high demand due to their low cost and ease of installation, and they are capable of protecting from impacts of a very broad spectrum in terms of energy. In this work, the objective is the optimization of material in each component, so that the energy absorbed per unit of mass is the main variable to take into account. For the development of the research, it was necessary to know the physical and mechanical properties of the rocks to determine the friction angle, which helped us to determine the limit value of slip resistance. A total of 40 linear meters were investigated with the aim of designing dynamic barriers, which were designed to achieve the optimal retention capacity of the rocks. It has been concluded that dynamic barriers meet their effectiveness by reducing the impact of the rock flow that affects the population, this evaluation is easy and 11 concrete to develop for any evaluator. It also recommends that the study can be refined in the future with the validation of more research projects that facilitate installation and improve performance where dynamic barriers need to be placed.
