Design & Economic Analysis of Heavy Haul Railway Prestressed Concrete Bridge
摘要
Abstract
With respect to the construction of the first heavy haul railway in central and southern part of shanxi , this paper addresses the rational design of prestressed concrete beam bridge on heavy haul railway based on the engineering design and economic analysis of series of simple supported T beam and continuous beam. Comparative analysis is conducted of the beam and the upper and lower structure material dosage and the linear meter cost on the basis of the design and research on the live load and overload in conventional span under two load modes of series of simply supported T beam and continuous beam, and to draw out the map of concrete beam bridge and track. The main conclusions are as follows:(1) when the live load of prestressed concrete beam is calculated in the case of the heavy haul train, its material consumption value is less than its carrying capacity improvement value;(2) when the live load is calculated with the heavy haul train, the impact on the infrastructure is smaller.关键词
