摘要
为了研究滨海淤泥质软土特性随深度的变化规律,以福州连江可门港区域软土为例,对所取试样进行了三轴剪切试验及界限含水率试验,对比分析了试样有效粘聚力Cu'、有效摩擦角φu'、粘聚力Cu、内摩擦角φu强度指标随深度的变化规律,以及液塑限指数随深度的变化规律。试验结果表明:随着深度的变化,物理特性指标变化较小,基本力学参数变化较明显。
In order to study the relationship between the characteristics of the coastal mucky soft soil and the depth,triaxial tests and the moisture limit tests for the soft soil in Lian-jiang Harbour area in Fuzhou,was carried out as an case. The relationships between the effective cohesion Cu ',effective friction angleφu',cohesion Cu,internal friction angle φu,liquid-plastic limit index and the depth were analyzed. The results show that,with the change of depth,liquid limit,plastic limit,plasticity index have little change,while the mechanical parameters change better.
