红粘土的强度机理
Shear strength proprieties of red clay
摘要
Abstract
Compared with common clay,the strength behavior of red clay which contains cementing material is more complicated.Research on the water-sensitive properties,degree of compaction and adhesion action of the red clay shows that the shear strength and cohesion of samples appear double stress peak value with the solution concentration increased.The shear strength and cohesion increase with the increase of dry densities.When the dry density of specimen is larger,the change of internal friction angle is more obvious.To investigate the effect of cementing on the strength of the red clay,the shearing tests were performed on the specimen saturated with the glycerol solution instead of water.Test result shows that the strength of the red clay decreases rapidly with the decrease of the cementing material.The variation laws of strength of red clays is also analyzed from the ce-menting effect.关键词
