Quantitative assessment on the variation of compressibility of Wenzhou marine clay during destructuration

摘要: A series of oedometer test were performed on both undisturbed and remolded specimens Wenzhou marine clay to quantitatively investigate the degradation soil structure during compression. The laboratory tests show that swell index natural increase with in consolidation stress. Hence, normalizing parameter ‘swell sensitivity’, termed as ratio swelling index, can only be regarded a qualitative parameter. On other hand, normalized stress sensitivity has good parabolic relationship destructuration. This result indicates used quantitative interpretation for clay. Comparison between additional void destructuration shows variation represented by are essentially same. In addition, formulating level is correlated at liquid limit.
