Abstract
Generalized test results of 120 soft foundation projects all around Ningbo area and by adopting methods of mathematical statistic and geotechnical test,the physical and mechanical indexes,relationship between these indexes and major parameters of consolidation of typical mucky clay in Ningbo area were systematically analyzed.Unique features of engineering characteristics were illustrated by compared Ningbo soft clay with other soft clays in China.Conclusions were obtained from the results that correlation between water content and void ratio, unit weight and void ratio and liquid limit and plastic limit were considerable perfect.Empirical formula for soft clay in Ningbo which based on these relation curves were different from other areas.Besides,structural characteristics has rather large effect on engineering properties of soft clay such as coefficient of consolidation and coefficient of secondary consolidation,also these effects were different from other areas.
