张峰水库砂页岩中泥化夹层对工程稳定性影响分析

Analysis on the Influence of Clay Interlayer in Sandy Shale on Zhangfeng Reservoir's Works Stability

文中以山西省张峰水库工程为依据,在大量现场试验资料的基础上,通过对该软弱夹层的特征、成因、勘察方法及其物理力学性质指标的分析和研究,评价其对工程的影响,提出了工程处理措施,为工程设计提供了可靠的地质依据,也为其他位于砂页岩中的中小型水利工程提供借鉴。

On the basis of major data of field tests in Zhangfeng Reservoir of Shanxi Province, the paper analyzes and studies the features, the formation causes, the exploration survey methods and the physico - mechanical property indexes of the weak interlayer, assesses its influence on works, puts forward engineering tredtment measure. All of these provide reliable geology basis for engineering design and also provide the reference to other midde or small sized hydraulic projects in sandy shale area.
