摘要
随着近年来高速铁路工程建设的日益发展,对无砟轨道建筑技术的要求越来越高。不过在实际建造过程中,无砟轨道还面临较多施工难题,如刚度控制、沉降控制、线性控制等。要满足工程建设特点,首先必须对这些施工难题加以分析。以成兰铁路站前工程11标工程为例,对高速铁路无砟轨道施工过程中的重难点进行细部分析,并通过对分析结果和工程实例的研究获得有价值的信息。
With the development of high-speed railway construction in recent years,the demand for ballastless track construction technology is increasing.However,in the actual construction process,ballastless track is still faced with many construction problems,such as stiffness control,settlement control,linear control and so on.In order to meet the characteristics of engineering construction,these construction problems must be analyzed firstly.Taking section 11 of Chengdu-Lanzhou Railway station front engineering as an example,this paper analyzes the key and difficult points in the construction process of ballastless track of high-speed railway in detail,and valuable information through the study of the analysis results and engineering examples is obtained.
