【摘要】 在详细考虑了红层边坡岩体的特征之后,选择了4个对岩体结构和边坡稳定性影响最大的因素,作为红层边坡岩体结构类型划分的依据:红层岩层面、层间软弱夹层的特征及其与边坡面相互交切的关系;岩体中的构造结构面的发育情况和组合特征及其与边坡面的交切关系;红层边坡岩体岩性的组合特征;上覆堆积土的红层边坡岩体的二元结构。按红层边坡岩体结构状态,把红层边坡岩体结构划分为4种,然后又按红层边坡岩体的岩性组合特征、岩层产状与坡面产状的关系、结构面的发育情况及其与坡面的关系、以及上覆堆积土的边坡岩体的坡顶线形状和岩土组合特征细分为13个类型和亚类。该分类详细,分类表中附有各类边坡岩体结构的工程地质评价、易发生的病害类型和工程建议,便于实际应用和推广。更多还原

【Abstract】 Based on the detailed consideration on the characteristics of rockmass in slope of red bed,4 pivotal factors were adopted to demarcate different structure styles of rockmass in slope of red bed.The factors included the characters of terranes and weak interbeds and the intersections with slope surface;the characters and combinations of structure joints and the intersections with slope surface;combinations of lithology;dualistic structure of M-shaped slope made up of red rockmass and overlying deposit soil.According to above-mentioned factors,4 categories including 13 subcategories were presented in detail,and engineering geological evaluation,incidental hazard styles and engineering advices were provided for each subcategory.更多还原
