软弱地基站场土方填筑施工技术研究与应用

RESEARCH AND APPLICATION OF CONSTRUCTION TECHNOLOGY OF SOFT GROUND STATION EARTHWORK FILLING

随着轨道交通陆续的开发,其车辆段基地也相应增多,有必要对轨道交通的路基进行更深的研究。国家铁路路基的承载对象与城市轨道交通的差异较大,其次城市的区域性特点与国铁适用范围存在明显差异。文中将从站场路基填料选择、站场路基原地基处理、站场路基填筑施工、路基填筑标高控制、路基施工质量及控制标准等方面进行研究,对填料配比、参照标准和施工质量控制进行优化,为今后类似工程提供借鉴。

With the continuous development of rail transit, the base of the depot also increased accordingly, it is necessary for rail transit subgrade for further study. There are significant differences between the carrying capacity of the national railway subgrade and the urban rail transit, and the regional characteristics of the city are obviously different from the scope of application of the national railway. In this paper, we will study the subgrade fill from the station, the foundation of the station subgrade, the construction of the roadbed, the roadbed filling elevation control, the construction quality and the control standard of the roadbed. Roadbed foundation treatment, station roadbed filling construction, roadbed filling elevation control, roadbed eonstruc.tion quality and control standards and the other aspects. The packing ratio, reference standard and construction quality control are optimized, which provides reference for similar projects in the future.
