| 摘 要： | 红粘土是一种区域性特殊土,含水量对其抗剪强度的影响与一般粘性土的规律不尽相同。通过室内直剪试验研究发现,含水量与红粘土粘聚力存在阶梯状相关关系,并且根据最小二乘法原理可以将其拟舍为多项式函数表达式。另外,随着含水量的增加,红粘土的内摩擦角变化不显著,呈微幅度波动状态。

| Abstract: | Red clay is a territorial peculiar soil. Its rule of the dependence relation of water content and shearing strength is that of general clay. It was found that water content had ladder-like relation to cohesion in red clay by directly shearing test and the relation can be simulated to polynomial function according to least square method. In addition, with the water increasing, the change of the fraction angle of red clay was indistinct, only small extent fluctuating. |
