论弄弄坪第四纪地层与工程地质问题

ON SOME PROBLEMS ABOUT QUATERNARY STRATIGRAPHY AND ENGINEERING GEOLOGY IN NONGNONGPING AREA,WESTERN SICHUAN PROVINCE

在野外考察与室内分析基础上,对弄弄坪地区工程地质基础等问题,如第四纪地层成因类型的鉴定、第四纪地层层序的建立以及第四纪地层时代的下限确定等进行了分析与讨论。

Nongnongping is located in the area of intensive earthquake and engineering construction is closely related to geoloical base. In the light of field survey and experiment analysis, some Quaternary problems are discussed such as cause, type, order of Quaternary strata and lower limit of Quaternary. Quaternary stratum system is established, basic engineering geological problems are studied and riliable conclusion is presented.
