摘　　要：自密实混凝土相比普通混凝土,具有流动性能好、不需要振捣等优点,应用范围广。本文综述了自密实混凝土材料自身性能包括的影响。简单介绍了CRTSIII型板式无砟轨道自密实混凝土的灌注工装、施工质量控制以及CRTSIII无砟轨道层间离缝、伤损研究。最后,提出了当前研究存在的一些问题和将来的研究方向,尽管国内外已在自密实混凝土材料的工作性能、力学性能、及其与环境的动、静荷载耦合问题等方面做了大量的研究,但CRTSIII无砟轨道基础结构动态演化机制缺乏研究。Compared with ordinary concrete, self-compacting concrete has the advantages of good mobility and no vibration, and has a wide range of applications. This paper reviews the effects of the properties of self-compacting concrete material included. This paper introduces the construction quality control of CRTSIII-type ballastless track and the study of CRTSIII ballastless track. Finally, some problems and future research direction are proposed. Although much research has been done in the working performance, mechanical properties and static load coupling with environment, the dynamic evolution mechanism of CRTSIII ballastless track infrastructure is lacking at home and abroad.
