摘要
为科学控制青膏泥的回填质量,在对青膏泥特性了解的基础上,通过液、塑限试验,干密度与含水率关系试验等科技手段,对青膏泥进行了系统的研究,结果表明:青膏泥为粉土,最大干密度时的含水率在16.7%左右,这一结论为施工提供了可靠的理论指导。同时,压实试验表明:压实系数均在0.90以上,说明达到了回填强度要求。
The Qinggaoni from the mausoleum of Yue Kindom was studied to improve the engineering quality through some tests such as liquid limit test,plastic limit test,the compaction test.Tests showed that it is silt and its water content is 16.7% when it is the maximum dry density.Tests also showed that the compaction coefficient of backfilled Qinggaoni is above 0.90.which implies its compaction coefficient is satisfied with strength requirement.
