杭衢铁路40m梁经济性分析

Economic Analysis of 40m Beam of Hangzhou-Quzhou Railway

随着国民经济的发展,高速铁路客运专线项目越来越多,与普通铁路相比,高速铁路客运专线上的桥梁所占线路总长比例大,桥梁标准梁型的选择及其经济性非常重要。论文结合40m梁在杭衢铁路上的运用情况,分别从墩身、承台、桩基圬工等方面与常规32m梁方案进行了比较分析,通过比较得出杭衢铁路40m梁方案在工程量及工程投资上的节省情况,为后续40m梁在其他工程项目中的运用提供参考。

With the development of national economy,the construction of the high-speed railway of passenger line is accelerating.Compared with ordinary railway,the bridge on high-speed railway passenger dedicated line accounts for a large proportion of the total length of the line,so the choice of standard beam type and its economy are very important.Based on the application of 40m beam in Hangzhou-Quzhou railway,this paper makes a comparative analysis with conventional 32m beam in pier body,cap and pile foundation masonry.Through comparison,the savings of 40m beam scheme in engineering quantity and investment of Hangzhou-Quzhou railway are obtained.It provides a reference for the subsequent application of 40m beam in other engineering projects.
