| 摘 要： | 针对鄂西南地区三叠系巴东组红层边坡中存在的软弱夹层,从地质沉积历史入手,通过区域构造力学分析,并结合矿物分析和粒度分析,对夹层的成因及其形成过程中矿物成分和粒度成分的变化进行了分析研究,同时结合相关室内试验对夹层的膨胀性和强度特性进行了分析研究,对该地区巴东组红层边坡夹层从成因到特性有了系统的认识,可为同类型地区工程建设的设计和施工提供参考。

| Abstract: | According to the weak mud intercalation existed in the red-bed slope of Triassic period in southwestern Hubei Province,we studied the genesis of the intercalation from the geological sedimentary history and regional tectonic mechanics,and analyzed the changing of mineral and grain size during its formation.By doing indoor test we studied the strength characteristics and expansibilities of weak intercalation.After the research we made whole understanding of intercalation in this region from genesis to charac... |
