面板堆石坝填筑材料碾压试验对填筑标准及参数的研究

ROLLING TEST FOR FILLING MATERIALS OF FACED ROCKFILL DAM AND THE STUDY OF PARAMETERS

面板堆石坝具有技术成熟、性能优越、造价低等优点,加上贵州地区出露地层主要以石灰岩为主,且其分布广泛,岩性均一,易于开采,是很好的面板堆石坝的填筑材料,因此面板堆石坝在贵州地区广泛应用。通过对大坝填筑前的碾压试验,探讨总结坝体填筑的质量控制要点及填筑标准参数。

Faced rockfill dam has the advantages of mature technology,superior performance and low cost.In addition,the outcrop layer in Guizhou area is mainly limestone,which is widely distributed,uniform lithology and easy to exploit.Faced rockfill dam is a good filling material for faced rockfill dam.Through rolling test before dam filling,the main points of dam quality control and standard parameters of dam filling are discussed and summarized.
