Experimental Study on Compaction Characteristics of High Liquid Limit Clay of The Yellow River Alluvial Plain and Its Subgrades Filling Technology

摘要

Based on the geologic exploration materials and indoor test of Ji-He expressway,analysed the compaction characteristics of high liquid limit clay of the Yellow River alluvial plain,the relationship among compaction work and moisture content and dry unit weight,and the changing rules of the CBR value in different compaction works with the change of moisture content.Demonstrated that high liquid limit clay of the Yellow River alluvial plain can be used in expressway subgrades filling. Moreover, through the experimental sections of subgrades filling,the reasonable construction technology and quality controlling measures is put forward, and provides reference of subgrades filling with high liquid limit clay of the Yellow River alluvial plain.
