摘要
红层在我国分布广泛,其岩性呈现多样性和不均匀性,粘土矿物含量高,化学成分以次生S iO2及倍半氧化物为主。红层具有膨胀崩解的特性,软化系数较低。在红层边坡中易产生崩塌落石、风化剥落及滑坡等地质灾害,并提出相应的防治措施。
Red bed, widely distributed in China, has lithologic diversity and heterogeneity, a high clay minerals content,and its main chemical compositions are secondary SiO2 and sesquioxide. Red bed is characterized by easy swelled and disintegrated, and has low coefficient of softening. Collapse and rockfall, weathering and spalling, and landslide are main geologic hazards in red bed slopes, then some prevention and control measures are presented.
