摘　　要：针对排矸石、矿渣、粉煤灰等固体废弃物占用大量的耕地并对生态环境造成污染的问题,对阜新地区大巴沟隧道排矸石、发电厂排放的粉煤灰等进行了物理、力学性质检测.在获得矸石、粉煤灰等基本性质指标的基础上,为进一步研究其应用价值,将矸石破碎做粗骨料、用磨细矿渣和粉煤灰做掺合料成功配制出高抗渗混凝土,混凝土的抗压强度达到48 MPa,劈拉强度达到5.5 MPa,抗渗等级超过P30.研究成果对我国老工业矿区特别是阜新矿区的三废治理具有现实指导意义,并具有良好的社会、环境和经济效益.研究中运用了均匀设计、SPSS、MATLIB、SEM-EDAX、神经网络等先进技术,并探讨了显微结构与抗渗等级的关系.The waste solid, for example, waste rock, slag and fly ash, takes over huge amount of land and causes environmental pollution. For this reason, conducted experimental research on the physical mechanical performance of the tunnel＇s waste rock of Dabagou, fuxin, and then got the physical mechanical performance index. For further study on its application value, the waste rock was broken as the coarse aggregates of high water-tight concrete with milled slag and fly ash. The experiment shows the compression strength of the concrete reaches 48 MPa, the shearing strength is 5.5 MPa, and the impervious grade exceeds P30. In this research, we applied a lot of advanced technology and softwares, e. g, uniformity analysis method, SPSS, SEM-EDAX and neural network technology. Furthermore, this paper studies the relation among micro-structure and impervious grade and the strength of concrete. We believe the result of the research can solve the problem of ＂three wastes＂ pollution and lack of stones, get very good social and economic effect, and be applied in wide-ranged field.
