摘　　要：黑云母富集带分布于银江水电站右岸边坡,具有性状差,分布范围广等特征,对边坡稳定极为不利。而边坡的稳定直接影响到电站的建设和运行安全,因此,分析黑云母富集带在右岸边坡的分布及其特性对于边坡开挖支护方案的确定、施工方案的研究以及施工过程中的预测预报具有重要意义。通过对前期勘察资料进行分析研究、结合已开挖揭露出的黑云母富集带性状特征确定了有针对性的治理措施,为右岸边坡的稳定及开挖工作按时、顺利完成提供了技术保障,所取得的经验可供类似工程勘察设计施工时参考。Biotite enrichment zone is distributed in the right bank slope of Yinjiang Hydropower Project.It has the characteristics of poor properties,wide distribution and dispersion,which is unfavorable to slope stability.The stability of the slope directly affects the construction and operation safety of the project,so the analysis of the distribution and characteristics of biotite enrichment zone on the right bank slope is of great significance for the determination of the slope excavation and support scheme,the study of the construction scheme and the prediction during the construction process.The corresponding treatments have been determined through the preliminary investigation data,combined with the excavated biotite enrichment zone characteristics,which provide technical support for the stability of the right bank slope and the smooth completion of the excavation work on time.The experience can provide reference for the survey,design and construction of other similar projects.
