摘要
根据广州新客站地区河道治理工程地质勘察成果,对该区软土的工程地质特征进行了探讨和总结,并根据200余组软土试验成果,对其物理力学参数相关性进行了统计和分析.结果表明,该区软土含水率和孔隙比的线性拟合程度最好,其压缩系数分别与含水率和孔隙比之间存在显著的线性相关关系,所建立的相关方程可用于由物理参数估算软土的压缩性参数.
According to the geological survey results of the watercourse management project in the area of Guangzhou New Railway Station,engineering geological characteristics of the soft soil were discussed and summarized and based on more than 200 test results of the soft soil,the statistics and analysis about physical and mechanical parameters were carried on.It showed that the linear fit of the moisture content and the void ratio of the soft soil in the area were best,and there were significant linear relationships between its compression coefficient and porosity as well as the moisture content.The relevant equations established could be used in estimating the compressibility parameters of the soft soil by its physical parameters.
