智能压实系统在兰新二线路基施工中的应用

The application of intelligent compaction system on the subgrade construction of Lanzhou-Xinjiang second line

现阶段新修的客专、高速铁路工程中路基占有很大比例,路基施工往往是整个线路的关键环节。为确保路基质量,加强过程控制,兰新第二双线施工中引入连续压实检验控制技术即智能压实系统,这也是第一次在铁路工程建设中大面积应用,有效地控制了路基施工质量,提高了施工效率,取得了良好的经济效益。

At the present stage, subgrade construction account for a large proportion of passenger train and bullet train construction. To ensure the quality of subgrade, strengthen the process control, continuous compaction test control technology (intelligent compaction system) was applied to Lanzhou-Xinjiang second line, this was the first time to extensively apply to rail construction project, controlled the roadbed construction quality effectively, improved the construction efficiency and achieved good economic benefit.
