摘要
高液限粘土易开裂,可压实性差,水稳定性欠佳,且在我国南方地区广泛分布,合理利用高液限粘土具有现实意义。在分析高液限粘土不饱和土理论、高液限粘土包芯机理和改良机理的基础上,系统地提出了高液限粘土的设计方法及设计参数,并得出了高液限粘土的典型设计结构和适用条件,为工程设计及工程决策发挥了重要的作用。
High liquid limit clay is easy to crack and has poor compactness and unsatisfactory water stability, and further, it is distributed widely in the southern area of China. Thus, rational use of high liquid limit clay is practical meaningful. On the basis of analyzing the unsaturated soil theory, core mechanism and improvement mechanism of high liquid limit clay, the design method and design parameters of it are systematically put forward, and meanwhile its typical design structure and suitable conditions are got. All of these can play the very vital role in project design and engineering decision.
