【摘要】：在鐵路車站附近,為了減少兩端線路路堤高度,降低工程投資,同時能夠滿足跨越的立交道路及河流防洪要求,可以采用建筑結(jié)構(gòu)較低的下承式橋槽形梁結(jié)構(gòu)形式。以新建石家莊至濟南鐵路客運專線工程跨越禹王路的工點槽形梁結(jié)構(gòu)為背景,通過有限元軟件進行結(jié)構(gòu)分析計算和設(shè)計優(yōu)化,介紹雙線鐵路槽形梁結(jié)構(gòu)的設(shè)計研究分析以及對槽形梁的空間結(jié)構(gòu)計算、空間動力特性及車線橋耦合動力分析,綜合考慮槽形梁彎剪扭綜合效應以及箱形邊主梁截面的空間變形。目前槽形連續(xù)梁在高速鐵路工程中的應用均較少,缺乏具體的經(jīng)驗和理論公式,解決此技術(shù)難題為類似橋梁設(shè)計工作提供重要參考。
[Abstract]:Near railway stations, in order to reduce the height of embankments at both ends of the lines, reduce the investment of projects, and meet the requirements of overpass roads and rivers for flood control, It can be used as the structure form of the through type bridge with lower building structure, taking the construction of the new Shijiazhuang to Jinan railway passenger dedicated line project across the Yuwang Road as the background, In this paper, the structure analysis and design optimization are carried out by finite element software, and the design research and analysis of the groove beam structure of double-track railway are introduced. The spatial structure calculation, spatial dynamic characteristics and vehicle-bridge coupling dynamic analysis of the groove beam are introduced. Considering the comprehensive effect of bending, shear and torsion of grooved beam and the spatial deformation of box side main beam section, the application of slot continuous beam in high speed railway engineering is few, and the concrete experience and theoretical formula are lacking. Solving this technical problem provides an important reference for similar bridge design.
