摘要
以山区某地方重载铁路增建二线工程为例,选取一处代表性的桥梁工点,分别采用1×32 m简支T梁+1×(32+48+32)m连续梁、1×(64+64)m T构2个桥式方案,通过综合分析对既有线的影响、水文条件、工程经济性、施工组织、景观要求等因素,选择采用1×(64+64)m T构的桥式方案。
This article takes the adding second line project of a heavy haul railway in a mountainous area as an example,selects a representative bridge construction site,and adopts two bridge type schemes:1×32 m simply supported T-beam+1×(32+48+32)m continuous beam and 1×(64+64)m T-structure.Through comprehensive analysis of factors such as the impact on the existing line,hydrological conditions,engineering economy,construction organization,and landscape requirements,the 1×(64+64)m T-structure bridge type scheme is selected.
