南水北调中线工程京石段S7标渠堤填筑现场碾压试验参数分析

The Research of Canals and Dams Filling Roller Compacted Field Test on Shijiazhuang-Beijing Segment S7 Sign in Mid-route of South-to-North Water Transfer

土方填筑是南水北调工程建设的主要内容之一,土方填筑施工参数是控制施工质量的定量标准,也是控制施工成本的关键,而科学合理的碾压参数、高效的施工方法以及相应的控制指标是通过现场碾压试验可以获得的。通过工程实例阐述了现场碾压试验的全过程以及施工参数确定的方法,对其试验参数进行了分析。

Earthwork filling is one of main contents of South-to-North Water Transfer Project, its parameter is the quantitative standard of controlling construction quality and the key of controlling construction cost. We can acquire the scientific and reasonable roller compacted parameter, high-efficient construction method and corresponding controlled index through the rolling test. This paper tells the whole process of rolling test and the way of solving construction parameter from engineering case, and analyses the parameter.
