摘要
“红层”在中国最早由李四光提出,主要指侏罗系、白垩系及少量三叠系及早古近系形成,主色调为红色的泥岩、页岩、粉砂岩、砂岩等岩性的一套陆相及浅水湖相沉积物。本文以姚安县为例,针对滇中“红层”区地质灾害进行风险评价研究,为后续该红层区域地质灾害防治及风险防控提供一定数据基础与理论依据。
“Red beds”were firstly proposed by Li Si-guang in China,which refers to a set of terrestrial and shallow lake sediments,such as mudstone,shale,siltstone and sandstonewith amain color tone of red,mainly formed in the Jurassic and Cretaceous,and a small amount in Triassic and early Paleogene.In this study,a risk assessment study was conducted on geological hazards in the“red beds”area in Yao an County,central Yunnan,which provide a certain data foundation and theoretical basis for further prevention and control of geological hazards and risks in the red beds area.
