CLIENT: Comisión Ejecutiva Hidroeléctrica del río Lempa

LOCATION: Carolina (El Salvador)

KEY ELEMENTS: One of the main issues of this type of bridge lies on the erection method, because the arch is built in cantilever and must be suspended by cable stays until it is closed. A temporary tower has been designed to anchor the front and back cable stays during this construction stage.

SERVICES: Feasiblity Studies/Conceptual Design, Detailed Design

BUDGET: US$ 5 million

PROJECT DURATION: Design 2009

PEDELTA’S KEY PERSONNEL: Javier Jordán, MSc, PE; Juan A. Sobrino, PhD, PEng, PE; Agnés Curràs, MSc; Rafael Cabral, MSc

PROJECT DESCRIPTION

This new arch bridge crosses the newly constructed reservoir over the Torola River in the Municipality of Carolina, El Salvador. The project comprises the detailed structural design and analysis of the arch structure as well as the roadway access design to both bridge approaches.

The Arch Bridge over Torola River is a 469 ft (143 m) structure with a 27 ft (8.5 m) wide concrete deck. The deck structure is supported by two parallel cast-in-place reinforced concrete arches erected using cantilever construction methods and tiebacks.

 

DESIGN/CONSTRUCTION APPROACH

The arch main span is 262 ft (80 m) long with a vertical clearance of 68 (21 m). The deck is a continuous concrete girder with a double-tee as its cross section, built using span-by-span construction methods and traveler form as false work.

The substructure is designed using shallow foundation techniques with vertical anchorages on some of its footings to provide an extra load needed for stabilization during the different construction stages.
