A series of compression tests and cyclic triaxial shear tests under different consolidation stress are performed on the typical structural soft soil in Binhai region of oft-com:office:smarttags" />Tianjin, which reveals the law of cyclic deformation under dynamic loading. The results show that the static deformation of structural soft clay can be divided into three parts by preconsolidation stress and structural yield stress. The relation curve of cyclic strain with cycle number under different consolidation stress has a critical dynamic stress ratio, which is not a fixed value, but reduces as the pressure increases.
