【摘要】：在水電工程中,地質條件對工程設計方案的選擇和建設的順利實施具有至關重要的影響,巖性條件的好壞對于巖體承載能力大小、支護設計形式和加固強度選擇等更是起到決定性作用。以某水電站的淺變質粉砂質板巖為主要研究對象,在其礦物成分分析的基礎上,進行巖石物理力學性質試驗、巖石中剪試驗、巖體變形試驗、巖體變形試驗配套聲測等各項物理力學試驗,通過試驗數據可知粉砂質板巖垂直板理和平行板理方向具有明顯的各向異性的物理力學特征。本文針對粉砂質板巖該特性,分析其間的相關性,將該區(qū)域巖體特征更好的利用,以服務于工程建設。對于類似巖性條件的各類工程具有很好的實際參考意義。
[Abstract]:In hydropower projects, geological conditions have a vital impact on the selection of engineering design schemes and the smooth implementation of construction, and the lithologic conditions are of great importance to the bearing capacity of rock mass. Support design form and reinforcement strength selection play a decisive role. Taking the shallow metamorphic silty slate of a hydropower station as the main research object, on the basis of the analysis of its mineral composition, the physical and mechanical properties of rock, the shear test in rock, the deformation test of rock mass are carried out. The physical and mechanical tests such as acoustic measurement of rock mass deformation test show that the vertical slate of silty slate has obvious anisotropic physical and mechanical characteristics in the direction of vertical slate and the direction of the slate. According to the characteristics of silty slate, this paper analyzes the correlation between them, and makes better use of the characteristics of rock mass in this area to serve the engineering construction. For similar lithologic conditions of various types of engineering has a good practical reference significance.
