白杨镇水库混凝土面板坝坝料碾压试验研究

Study on compaction test of dam material covered with concrete faceplate in Baiyangzhen reservoir

为了得到准确的坝料碾压指标,本文对白杨镇水库坝料进行了室内的不同含砾率下的相对密度试验和现场碾压试验。室内试验得到了坝料的标准曲线,并通过现场碾压试验对曲线进行修正,使给出的标准曲线能准确的控制坝体填筑的质量;并结合现场碾压试验给出了合理的坝料填筑的碾压参数,为面板堆石坝填筑过程中的质量控制提供可靠依据。

In order to get accurate dam material rolling indicator,the paper conducted the indoor relative density and in-situ roller compaction test to Baiyangzhen reservoir dam material under different gravel content.The indoor test obtained the standard curve of dam material,and correct the curve through the field rolling test,so the standard curve can accurately control the quality of dam filling; combined with the field compaction test,it gave the resonable rolling parameters of dam filling.The result can provide reliable basis for the quality control in construction of concrete face rockfill dam.
