| 摘 要： | 采用渗透系数法研究了轴向压力以及强度对铁尾矿砂混凝土抗渗性的影响。研究表明：铁尾矿砂混凝土在轴向压力作用下，其抗渗性并非一直在劣化，而是在荷载水平0．3—0．4时逐渐提高；当荷载水平为0．4时，出现有压状态下的最大值。当荷载水平超过0．5时，铁尾矿砂混凝土抗渗性能开始快速下降。铁尾矿砂混凝土相对渗透系数与强度之间存在明显的线性关系，其抗渗性能随强度的增大而提高。

| Abstract: | Impermeability of iron tailing sand concrete under axial compression was studied by modified penetration coefficient method. The study results show that the impermeability of iron tailing sand concrete under axial compression become not always bad. When the load level is 0.3 - 0.4, impermeability increased gradually and impermeability appeared the highest state under pressure when the load level is 0.4. When the load level is higher than 0.5, the permeation resistance of concrete starts to decline rapidly. Significant linear relationship was found between relative permeability coefficient and strength of iron tailing sand concrete. With the strength increases, impermeability of iron tailing sand concrete Increase |
