摘要
Abstract
Based on a large number of tests during engineering investigation in levee projects of the Lower Yellow River,problems which related to plasticity chart and triangle coordinate classification were analyzed,and the relativity of the main index as well as the influence on permeability grade were studied. The results show that a remarkable linear relativity occurs between liquid limit and plasticity index from plasticity chart and clay content from classification of triangular coordinates. Heavy clay and clay roughly correspond with high liquid limit clay;silty clay and loam roughly correspond with low liquid limit clay(sandy);sandy loam class and silt roughly correspond with low liquid limit silt(sandy). Both these two classi-fication standards have the problem of crossing different permeating levels;permeability analysis reflects similar laws,which can be used roughly by contrast,however,the triangle coordinate classification is convenient for the assessment of permeating deformation.关键词
