摘    要：对几种水泥尾砂配比的全尾砂胶结充填体进行了无侧限条件下的变形试验,并首次对其抗拉强度和抗挠强度进行了对比试验,发现尾砂胶结充填体在无侧限条件下无明显压密过程,具有较大的侧向膨胀能力,其抗挠强度远比抗拉强度大等特征,进一步证明了这种充填体具有较强的塑性.

Abstract: Experiments in deformation of cement tailing backfill with several ratios between concrete and tailing under no lateral restriction and the first contrastive experiment between tensile strength and bending strength of the backfill are made. The result shows that the backtill has no obvious densifying process and has larger capability of lateral expansion under no lateral restriction, and its bending strength Mis much larger than its tensile strength, which shows that the cemented tailing back fill has a stronger plastic property.
