【摘要】：在水电工程中,地质条件对工程设计方案的选择和建设的顺利实施具有至关重要的影响,岩性条件的好坏对于岩体承载能力大小、支护设计形式和加固强度选择等更是起到决定性作用。以某水电站的浅变质粉砂质板岩为主要研究对象,在其矿物成分分析的基础上,进行岩石物理力学性质试验、岩石中剪试验、岩体变形试验、岩体变形试验配套声测等各项物理力学试验,通过试验数据可知粉砂质板岩垂直板理和平行板理方向具有明显的各向异性的物理力学特征。本文针对粉砂质板岩该特性,分析其间的相关性,将该区域岩体特征更好的利用,以服务于工程建设。对于类似岩性条件的各类工程具有很好的实际参考意义。
[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.
