STUDY OF STRUCTURAL ANALYSIS OF PSC BOX GIRDER VIADUCT FOR PUNE METRO

Abstract

Pune is a developing metropolitan city not only emerging as an international education hub but also as an IT and an ITES research and development centre, which attracts in migration of population in the city. The Population of Pune city is approximately 40 lacs and has registered 10, 70,000 vehicles. The survey which was conducted by PMC shows that volume to capacity ratio of the existing roads is more than 1.00 in peak hours. In this urbanized city, there is growing multi-modal commuting activity (public bus transport, two-wheelers, three wheelers, cars, and others). This activity is largely local, but rapid urbanization is increasing its traffic within the city. It is observed that, road public transport system in Pune city is not efficiently working as estimated because the existing roads do not have the capacity to carry vehicular load and high demand of traffic density. Hence, there is a need to study the traffic density to minimize the traffic congestion for efficient movement of traffic. With the available road width, as there are no chances of road widening possible, constructing a metro bridge at most congested routes is the only option to solve the traffic problems. In this project, the study is mainly focusing on analysis of advanced techniques for design of precast segmental box girder viaduct. The construction of metro rail bridge is one of the long term strategies for safe and efficient movement of commuter’s flow which provides fast, safe and non polluting way of transport system. The proposal of a precast segmental viaduct design is technically feasible as there is continuous traffic flow with limited availability of Right Of Way. An extensive study of all the parameters involved in the design of the bridge will be made. The project concisely summarizes the economical design of the bridge.
