路基基床表层级配碎石施工技术探索与实践

Research on Construction Technology of Graded Broken Stone on Roadbed Surface Layer

客运专线路基基床表层采用级配碎石作为填料,在我国铁路施工中是首次采用,其特点是技术新、工艺新、质量要求高,无成熟的经验可借鉴。以秦沈客运专线为依托,从配料选择、施工工艺和施工检测几个方面对级配碎石填料进行控制,形成独特的路基级配碎石施工技术。

It is the first time to use graded broken stone as stuffing on the roadbed surface layer of passenger special line in the railway construction in China. So the technology and craftwork are new; the quality requirement is high and there＇re no mature experiences to refer to. Taking Qinshen passenger special line for example, the article discussed how to control graded broken stone as stuffing from ingredient choosing, construction technology and construction examination and then formed unique construction technology of roadbed graded broken stone.
