| 摘 要： | 本文通过对人工制备的不同盐浓度的盐渍土的抗剪强度及其指标进行研究发现:随着土样中可溶性盐浓度的增加,土的粘聚力约呈线性下降的趋势,内摩擦角近似呈线性上升趋势.土样中的可溶性盐浓度在不同范围内变化时,其抗剪强度的变化趋势分别由粘聚力或内摩擦角决定.土祥的可溶性盐浓度与土样的抗剪强度、粘聚力、内摩擦角之间存在非常强的函数关系. |
| 关 键 词： | 盐浓度 粘性土 抗剪强度 |

| Abstract: | Through saline soil shear strength and its index of soil sample to different salt concentration by artificial preparation,this article study found: with the increase of the soluble salt concentration in the soil,the stick together about a linear force downward trend,and internal friction angle approximate linear rising trend.Soluble salt concentration in the soil samples in different range of change,the shear strength respectively by the changing trends of the cohesion or internal friction angle decision.There was very strong function relation between concentration of the soil soluble salt,shear strength,cohesion and internal friction angle. |
| Keywords: | Salt Concentration Cohesive Soil Shear Strength |
