Design adjustments in the constructionphase - a look beyond engineering
Abstract: In carrying out the work to excavate a road tunnel, parallel to the existing road, each open-pit rock blasting process aimed at conforming the portal structure would result in the traffic on the BR-101/SC highway being paralyzed for about two hours. This highway is one of the most important, in terms of traffic, in the southern region of Brazil. To minimize these interventions, the solution...

Refined flow to analyze the viability of tunnels in road planning
Abstract: When planning an improve the capacity of two-lanes highways, it is always sought to allocate the new road parallel to the existing lane, in order to facilitate the operations of maintenance by the owner, and the changes of direction for the users, when necessary. In this sense, in the beginning of the year 2000, the designs for upgrade from twolanes for four-lanes expressway of the road...

Simulation of stresses around tunnels from measurements of convergence and Overcoring Method
Abstract: During the excavation of the tunnel Morro Alto in the federal highway BR-101/RS was encountered faults along the longitudinal axis of the tunnel. After stabilization of deformations, the final convergence was less than 10 mm in the section close to the fault zone. Even with the apparent stability of the massive, cracks appeared in sprayed concrete line. From further research, it was identified...
