| 摘 要： | 从栗西尾矿堆积坝的岩土工程勘察、试验的大量数据出发,深入分析了堆积坝体尾矿砂土性状、堆积特性及其变化规律,研究了栗西尾矿砂土分布规律、物理力学性质随时间的变化规律,初步揭示了高堆尾矿坝深部抗剪指标要显著高于浅部;堆积坝体同一空间位置,同样埋深下干容重指标具有随时间明显增长、渗透系数明显降低的规律。

| Abstract: | Based on mass data of geotechnical investigation and soil test in Lixi tailings fill dam,this thesis makes a thorough analysis of tailings properties and its law of change,further investigates the law of distribution and change of physics-mechanics character of the variation with time in Lixi tailings fill dam.This thesis preliminarily reveals that high tailings dam＇s deep part shear strength index is greater than shallow part,under the circumstance of the same spatial location of piling dam body,the gravity index grows significantly as the time went by,the permeability coefficient becomes lower obviously. |
