摘　　要：CRTSⅢ型板式无砟轨道先张法预应力混凝土轨道板,是具有我国完全自主知识产权的高速铁路技术,也是目前最先进的高速铁路无砟轨道。轨道板采用C60高性能混凝土浇筑,提高轨道板使用的强度和耐久性,轨道板要求工厂化生产。为了提高轨道板生产质量和工厂化生产的要求,结合轨道板生产过程经验,研究了轨道板C60混凝土制备和浇筑工艺。主要包括,混凝土原材料、混凝土配合比设计计算、混凝土配比确定、混凝土拌和、混凝土浇筑、混凝土养护。Pre-tensioned prestressed CRTSⅢunballasted track slab is a new type of ballastless track on high speed railway with our own independent intellectual property rights.It is also the most advanced high-speed railway ballastless track at present.Track plate made of C60 high performance concrete can improve the strength and durability,and it needs factory production.In order to improve the quality of track plate and meet the requirements of the production process,combined with the experience of the track plate production process,this paper studied the preparation and pouring process of C60 concrete,mainly including concrete raw materials,concrete mix ratio design calculation,concrete ratio determination,concrete mixing,concrete pouring,concrete curing.
