摘要
为解决细粒弱盐渍土路堤压实的技术难题,通过试验,研究细粒弱盐渍土的压实特性,确定其最优的振动压实参数,并与相关规范提出的标准试验方法压实效果进行了对比。结果表明,振动压实可以使土体得到充分的压实,压实效果更好。建议:对于细粒弱盐渍土应采用振动压实方法确定其标准密度和最佳含水率。
In order to solve the technical problems of fine-grained weak saline soil subgrade compaction,this paper studied the compaction characteristics of the weak saline soil by experiment,determined the optimal vibration-compaction parameters,and compared with the compaction effect that relevant criterions proposed.The results show that vibration-compaction can make the soil fully compacted and compaction effect is better.Suggestion： it is best to adopt the vibration-compaction method to determine standard density and optimum water content.
