摘　　要：红层在湖南省分布广泛,其具有膨胀崩解的特性,软化系数较低的特征。因此红层边坡中易产生崩塌落石、风化剥落及滑坡等地质灾害,通过多年红层地区边坡支护治理经验总结红层地区的地层特性及红层地区地质灾害特点,对红层边坡的变形破坏机制、地质灾害防治等进行了较为全面的分析和研究。Red beds are widely distributed in Hunan Province,characterized by swelling and disintegration,and low softening coefficients.Therefore,geological disasters such as collapse,rockfall,weathering,and landslide are prone to occur in red bed slopes.Based on many years of experience in slope support and treatment in red bed areas,this paper summarizes the stratigraphic characteristics and geological disaster characteristics of red bed areas,and conducts a comprehensive analysis and research on the deformation and failure mechanism of high and steep red bed rock slopes,as well as geological disaster prevention and control.
