铁路客运专线原位制梁应用方案的技术经济分析

Cost-effectiveness Analysis of In-place Beam Casting Schemes of Passenger-dedicated Railway Bridge

运用技术经济分析法是对原位制梁方案进行成本优化的主要方法,使选用的方案能够更好地体现工程本身的适用性和经济性。文章首先是通过定性分析制梁方案的可行性,根据经验和应用方案的工程特征进行优缺点的对比,选用适用方案;又通过技术经济比较分析各个制梁方案的工程成本,以期得到优化的制梁方案。

Cost-effectiveness analysis is an important means to select out a in-place beam casting scheme that fulfills not only the applicability but also economical efficiency of the project. The operability of different beam casting schemes is analyzed; comparative.analysis of different schemes＇ technical merits is made according to the author＇s work expierencc and their different engineering features; and finally cost-effectiveness analysis of different schemes is used aiming to get an optimum in-place beam casting scheme.
