墩台是整个桥梁的重要组成部分。在新线铁路修建中除了一些大型的线路挡护工程,桥涵导流工程外,桥梁墩台的圬工工程量往往占主要比重。尤其是一些高桥更为突出。近几年来,我国新建的一些铁路大多处于山区。高桥在整个桥梁工程中占了很大比重。由于目前桥梁墩台的施工方法基本上还都是就地灌注或就地砌筑的,占用了大量劳动力、建筑材料和运输工具,工作条件比较艰巨,因此,如何改善桥梁墩台结构型式是关系到能否多、快、好、省修建铁路的重要问題,应该引起重视。
Pier is an important part of the bridge. In addition to some large-scale line protection works and bridges and culverts diversion project in the construction of the new railway line, the amount of construction work of bridge piers and piers often accounts for the major proportion. In particular, some Takahashi more prominent. In recent years, most of the new railroads in our country are located in mountainous areas. Takahashi in the bridge project accounted for a large proportion. Because the construction methods of bridge piers and abutments are basically all still in-situ perfusion or in-situ masonry, which occupy a large amount of labor force, building materials and transportation tools, working conditions are arduous. Therefore, how to improve the type of bridge piers and abutments is the relationship To whether more, faster, better, provincial important issue of railway construction, should pay attention.
