Abstract: Based on Tianjin marine soft clay, triaxial tests are carried out on the intact soil and remolded soil in different test conditions, such as consolidation pressure, stress path, loading rate, drainage condition. The structural damage is described by the relationship between stress ratio structural parameter and strain. The character of structural damage under different loading modes is studied. The results indicate that when the consolidation pressure is below structure yielding pressure, the initial structure and damage rate in the shearing stage are not influenced by consolidation pressure. When consolidation pressure is above structure yielding pressure, the initial structure and damage rate decrease with the increasing of consolidation pressure. When the direction angle of stress path ? is in the ranges of 0

Key words: soft clay, loading mode, character of structural damage, structural parameter
