A study of the formation of structure yield stress subject to creep of the soft dredger fill

Soil structure has a significant influence on its engineering mechanics behavior.To investigate the form of structure yield stress of the soils,the creep tests and micro-structure are conducted on the soft dredger fill in the Tianjin Binhai New Area.The results indicate that the influence of the creep on the soil structure is a comprehensive process,among them,drainage is the most critical condition.Base on this,the structure yield stress are effected by the cell pressure and deviator pressure,i...
