固化灰渣土路基动力特性及稳定性试验研究
Research on Experimental of Dynamic Characteristics and Stability of Solidified Ash Soil Subgrade
摘要
Abstract
Using the prepared curing agent,the ash residue and engineering waste soil were solidified,and dynamic characteristics and water stability tests of the road performance of the solidified ash residue soil were conducted to study the effects of curing agent dosage,confining pressure,and dynamic stress ratio.The results showed that with the increase of curing agent dosage,the dynamic elastic modulus of the sample increased significantly,and the damping ratio changed little;after 24 h of immersion,the dynamic elastic modulus of the sample decreased by 15%～20%,and the damping ratio increased to some extent;as the dynamic stress ratio increases,the dynamic elastic modulus weakens more significantly,while the damping ratio weakens less.The research conclusion can provide reference for the utilization of ash and the design and dynamic response analysis of solidified ash soil subgrade.关键词
