| 摘 要： | 结合《六盘山地区公路修筑技术研究》课题，针对六盘山地区广泛分布的细粒土含水量高的特点，分析目前规范中的压实标准及其存在的局限性，参考国内外成功经验，提出当采用天然稠度不小于1．25的细粒土填筑路基时，2级及2级以下公路以孔隙率控制压实，且孔隙率Va≤10％；当采用天然稠度（0．5≤稠度〈1．25）过湿土掺加生石灰处治后填筑路基时，建议以压实度为主、CBR为辅的双指标控制压实。

| Abstract: | In combination with the subject "Investigation of Construction Techniques for Highways in Liupan Mountain Area" and aiming at the high-water content feature of fine-grained soils extensively distributed in Liupan Mountain area,this paper analyzes the compaction standards and existing limitations in current specification.By reference of successful experiences at home and abroad the paper proposes that the compaction is controlled by porosity for class two and under class two highways when the fine-grained so... |
