| 摘 要： | 文章结合某尾矿库对尾矿料的物理力学性试验成果进行了系统的分析研究,得出了尾粉砂内摩擦角和孔隙比的关系,同时对尾矿的压缩性、抗剪强度等进行了详细的分析讨论,研究表明:尾矿的物理力学性及其与堆存深度的关系与一般的土有较大的区别,各种尾矿都具有一定的凝聚力,要增强坝体的稳定性,必须控制尾矿排放工艺,改善坝体的排水条件。

| Abstract: | Systematic analyses and studies of physical and mechanical properties are made on tailings test results in a mine. Correlation between the angle of internal fiction of silty tailings and void ratio are obtained. Detailed analyses and discussions are made of the compressibility and percolation of tailings. The tailings are different from general soil, considering the correlation of its physical and mechanical properties such as dry densities and water content to deposit depth. The studies show that all tailings have cohesion in fact. To increase dam stabilization, a reasonable technology of tailings letting and the drained condition improvement of dam are indispensable. |
