[Objective]This study focused on the surface energy characteristics of red-bed soft rocks during disin-tegration in the Shengzhou-Xinchang area of Zhejiang Province.[Methods]Based on the principle of energy dissi-pation,this study analyzed the conversion,transfer,and dissipation of energy during the process of disintegration under dry-wet cycles for three groups of red-bed soft rocks,considering different compositions in the study area.This study aimed to explore the law of energy absorption and transformation into surface energy during the process of red-bed soft rock disintegration.[Results]The results show that the surface energy accumulation of the red-bed soft rock in the study area undergoes three stages with an increasing number of dry-wet cycles:a slow growth stage,a rapid growth stage,and a stable stage.The results also indicate that the higher the content of clay minerals in the red-bed soft rock is,the more surface energy it generates,and the poorer its resistance to disintegration.[Conclu-sion]The energy dissipation model proposed in this study provides a reference for the governance of various failure problems of the red-bed soft rock in the Shengzhou-Xinchang area of Zhejiang Province.
