桂西南红层工程地质特性及工程效应研究——以驮英水库及灌区工程为例

Study of engineering geological characteristics and engineering effects of red bed in Southwest Guangxi

红层是桂西南重要并广泛分布的特殊岩体,强度低,遇水易软化,具较强蠕变性,常诱发地质灾害。本文以驮英水库及灌区工程红层为例,详细阐述了驮英工程地质环境,系统分析了主要工程地质问题,剖析地质灾害原因,并对桂西南红层地区主要工程地质问题提出工程建议。

Red beds are important special rock masses widely distributed in Southwest Guangxi.It often induces geo⁃logical disasters due to its low strength,easily softening in water and strong creep.Taking the red beds in the engi⁃neering area of Tuoying Reservoir Irrigation Zone Project as example,a detailed introduction was made on the engi⁃neering geological environment of the project,based on which the author analyzed the major engineering problems,the causes for geological disasters,and put forward suggestions for main engineering geological problems in the red bed area of Southwest Guangxi.
