广西天等锰矿尾矿坝填料特性试验研究

摘要

利用采区剥离土填筑尾矿坝,控制土石方填筑质量是工程的关键,而高质量填筑体的修筑成型,首先取决于对填料工程性质的充分掌握和合理利用.充分了解填料的工程性质,有利于正确、合理地指导设计和施工.通过室内试验研究,分析尾矿坝填料的特殊物理力学性质和工程性质,评价其用作填料的适宜性,并给出设计、施工所需关键参数,为设计和施工提供指导和帮助.%The critical of engineering is how to use the striping soil of mining area to fill the Tailing Dam to ensure the quality of rock fill earthwork. However, the high quality of rock fill earthwork is depended on the full understanding of the engineering prosperities and how to use it optimally. Full understanding about the engineering prosperities is good for guiding the design and construction correctly and rationally. By the Laboratory Experimental Studies, this thesis tries to analyze the special physical-mechanical properties and the engineering properties of the fill-materials of Tailing Dam,evaluate the suitability of using them as the fill materials,and then supply the needed critical parameters for design and construction, provide guidance and help for related design and construction.
