重型振动碾碾压堆石坝沉降量研究与分析

Research and analysis of settlement of rockfill dam compacted with heavy vibrating roller

通过对老挝南公1水电站工程施工期坝体沉降量、重型振动碾碾压振动试验的研究分析,绘制相应的关系曲线。通过数据对比及相关曲线分析得在重型振动碾碾压下,有助于提高面板堆石坝坝体碾压密实度,降低因碾压不实导致的坝体不均匀沉降。

Research and analysis of dam settlement and rolling vibration test of heavy vibrating roller were conducted during the construction period of Laos Nangong I Hydropower Project.Corresponding relationship curves were drawn.By comparing data and analyzing relevant curves,it is concluded that rolling with heavy vibrating roller is helpful to improve the rolling compactness of the face-slab rockfill dam body and reduce the uneven settlement of the dam body due to incomplete rolling.
