| 摘 要： | 采用室内试验和现场原型试验,对辽河石佛寺水库库区内掺入水泥后粉细砂的特性进行了研究。试验结果表明,随着水泥掺入量的增加,粉细砂的凝聚力和内摩擦角增大,渗透系数减小。当水泥的掺入量为2%时,抗剪强度指标和渗透系数已明显改善,而且在最不利的情况下满足对渗透变形的要求。粉细砂掺入水泥后,其性能得到了很大改善,用于修筑拦河主坝是完全可行的。

| Abstract: | Indoor and outdoor experiments on the characteristics of the cement added fine sands for Shifosi Reservoir were carried out.Experimental results show that;with the increase of cements,the cohesive force and friction angle increase;the percolation coefficient decreases.When the volume ratio of cement and fine sands is 2 %,shear strength and percolation coefficient are improved obviously.The properties of fine sands are improved when they are combined with cements,so using them in embankment is possible. |

| Keywords: | fine sands cement cohesive force percolation coefficient |
