摘要
针对龙溪口库区大量粉土地基不能直接作为堤防的持力层,且粉土废弃带来诸多环保方面不利影响等问题,开展了固化土(加石或不加石)筑堤材料的试验研究。通过一定量的胶凝材料和专用外加剂将土(石)胶结固化后,具有一定力学强度和抗渗性能等优点,胶固土(石)经过3 a泡水后未崩解,满足筑堤材料的强度要求。经过处理的粉土地基上建设胶固土(石)堤防具有创新性,新的建堤材料使粉土得到废物利用,固结材料特性比传统土石坝的散粒体材料具有更高的安全性,拓宽了建堤材料的应用范围,具有较好的推广应用价值。
Since a large amount of silt foundation in the Longxikou Reservoir area cannot be directly used as the bearing layer for embankments,and the disposal of silt will cause adverse environmental effects,this paper carries out experimental research on solidified soil(with or without stone)embankment materials.After a certain amount of cementitious materials and specialized additives are used to solidify the soil(stone),the cemented soil(stone)has certain advantages such as mechanical strength and impermeability and does not collapse after three years of soaking in water,meeting the strength requirements of embankment materials.The construction of cemented soil(stone)embankment on a silt foundation is innovative.The new embankment building materials enable waste utilization of silt.The safety of the consolidated material is higher than that of the granular material of the traditional embankment dam,and it broadens the application range of embankment building materials and has good promotion and application value.
