摘要
轨枕作为铁路工程中重要的预制构件之一,起着分散传递列车荷载,保证列车运行平稳、安全的重要作用。论文从混凝土轨枕施工中配合比设计、原材料选用及生产过程控制等几个方面进行探讨论述,提出了提高高原混凝土轨枕耐久性的措施,力求通过各相关措施的实施及控制,使所生产出的轨枕达到标准要求的各项常规及耐久性技术指标。
As one of the important prefabricated components in railway engineering,sleepers play an important role in dispersing the load of trains and ensuring the smooth and safe operation of trains.This paper discusses the mix proportion design,raw material selection and production process control in concrete sleeper construction,and puts forward measures to improve the durability of concrete sleepers in plateau.Through the implementation and control of relevant measures,the sleepers produced can meet the requirements of the standards of various conventional and durability technical indicators.
