摘要
通过室内大型三轴实验,研究了吉林台水库爆破料在不同级配下的应力应变关系,得到了在一定击实功下爆破料的最大干密度随细料含量变化的规律,分析了爆破料在不同级配和不同围压下应力与应变的变化规律、轴向应变与体积应变的关系及抗剪强度变化特性.从微观的角度说明了变化规律产生的原因,得出爆破料的抗剪强度随级配的变化而变化的规律.
According to large scale indoor triaxial compression tests, the relative change of the engineering properties of the Jilintai reservoir shot firing aggregate in different stages. The conclusion is that the maximum dry density of the shot firing aggregate with various content of fines gives a compactive effort. The relations between stress and strain, and between volumetric strain and axial strain have been analyzed. A reason for the change is shown to occur on a microcosmic scale with the component shear strength of the shot firing aggregate following the gradations.
