Abstract: It is difficult to describe the strain softening of geo-materials. In order to analyze softening mechanism of geo-materials in essence, it is necessary to combine the researches of softening mechanism with the researches of strain localization evolvement. The developments of strain localization researches in geotechnical mechanics, such as experimental researches, theoretical modeling and numerical simulations, have been reviewed. When strain localization happened, the necessity to consider the strain-gradient was illuminated. Some primary ideas about the trends of strain localization researches in geotechnical mechanics were put forward.

Key words: softening, geo-materials, strain localization, strain-gradient, trends
