摘要
以不同粒度的砂,在不同的含水量情况下,采用无侧限压缩试验的方法,研究非饱和砂的表观粘聚力与砂的粒度、含水量等的关系。试验表明,在研究范围内,非饱和砂的表观粘聚力随含水量的增加而升高,并且随粒度的减小而升高,随粒度的增大而减小。
With the method of unconfined compression test and under the condition of sand of multi - granularity and different water content, the relationship between the apparent cohesion of unsaturation sand and its granularity and water content shall be researched. The test shows that in the research extent, the apparent cohesion of unsaturation raises as the water content grows higher, increases as the granularity decreases, and reduced as the granularity enlar^es.
