摘要
通过尾砂胶结充填体配比试验,研究尾砂胶结充填体强度与试样尺寸和几何形状之间的关系。试验结果表明:在相同条件下,尾砂胶结充填体强度在试验范围内随试样尺寸的增加而减小,呈非线性变化;不同尺寸与几何形状的胶结充填体试样强度之间的换算比例关系为:Φ152 mm充填体试样强度大致为Φ72和Φ85mm试样强度的3/4,为70.7 mm立方体试样强度的3/5。
The relation of compressive strength of cemented tailings fill and size, geometries of cemented backfill is studied. The test results show under the same condition compressive strength of cemented tailings fill minishes with size increasing, it show itself non-linear variation. 150 mm diameter cylinder specimen fill strength averaged approximately three-quarter of 72 mm and 85 mm diameter cylinders specimen, about three fifths of 70.7 mm cubes specimen.
