A组填料在京沪高速铁路路基上的应用

Application of Group A Stuffing in Beijing-Shanghai Express Railway Roadbeds

通过试验段的填筑并收集数据,以确定应选用的填料,同时对规范中的个别数据做了证实,以数据选择机械设备及设备组合,确定路基压实遍数、填料的松铺系数等。介绍了路基施工工艺,以及对选料及试验段施工的体会。

By means of stuffing in the test section,data collection,the type of stuffing is fixed.Meanwhile,some data in the specification is testified,and machinery and equipment package are chosen according to the data,to determine the compaction times of roadbeds as well as the coefficient of loose stuffing laying.This paper introduces roadbed construction techniques, and understanding of stuffing selection and test section construction.
