Analysis of working conditions to which the triaduct is subjected in Roca Fuerte route - Manta

Abstract

In the work, the working conditions to which the triaduct is located in the Rocafuerte - Manta road are analyzed, with vehicle service conditions similar to those of a bridge since they share the same scenario. Despite their similarities, these two civil works, bridges and sewers, have a different structural behavior and design; The bridge sits on supports that are placed from end to end or in an intermediate way, while the sewer has a base that covers the entire area on which it will settle under a concept similar to that of a shoe or foundation slab, it also has with walls on its sides fulfilling the function of walls, which gives a drawer shape to this structure and hence its name. The working conditions of the aforementioned triaduct are analyzed, which are caused by vehicular traffic, earth thrusts, hydraulic flow, seismic load and a filler load that could be placed on the upper road slab that is not present on a bridge and corresponds to a dead load distributed because of the filling.
