低液限粉土的压实性能研究

结合子洲至靖边高速公路4个合同段的低液限粉土,采用试验和理论分析的方法,对该地区广泛存在的低液限粉土的压实性能进行了系统研究.首先,对该地区的低液限粉土进行了物理、力学性质试验,取得了基本的研究参数.其次,研究了低液限粉土的静力压实的机理和影响因素;基于长期稳定性的考虑,测定分析了CBR值,提出了考虑CBR值的低液限粉土的压实标准.

Study of Compaction Property for Low Liquid Limit Silt

Based on the low liquid limit silt got from 4 sections of ZiJing Expressway, the paper studies the compaction property of it systematicly by experiments and theoretical analysis. Firstly, the author does experiments in order to get the basic physical and technical parameters of the low liquid limit silt. Then, the paper studies the principle and influencing factors of static compaction. As to the long-term stability, the paper puts forward the compaction standards of low liquid limit silt after analysising ...
