Segmental Construction for Bridges in Hilly Areas: An Overview

Construction of bridges in hilly areas poses a unique problem to engineers. Each bridge site has own peculiarity and needs a specialized approach to deal with the situation. Deep gorges, fast flow of water, bouldery river beds, geological and topographical features, however, make the task of construction agencies tedious. In such situations, long span bridges designed on segmental construction technique has been found to be a very effective and efficient arrangement. BRO, which is primarily engaged in development of road infrastructure in hilly areas, faces this problem in a major way. A large number of long span bridges has been undertaken for construction using a segmental construction technique. A variety of span arrangement viz continuous, balanced cantilever and cantilever on open, well foundation and with/without monolithic construction with sub-structure has been adopted. All these bridges have been constructed using cast-in-situ construction, as limited space availability and difficulty in transportation do not favor adopting pre-cast segmental construction. This paper presents a case study of a bridge undertaken for construction using cast in situ segmental construction techniques and various aspects related to construction of such bridges.
