摘要
对湖南竹城公路K81K83段边坡的泥灰岩、灰页岩及不同岩性的弱面分别进行了变角度剪切试验和直剪试验,并运用费辛柯法和M.Georgi法对岩石抗剪强度和岩体弱面的剪切强度进行了合理的工程弱化折减,将为进一步的边坡稳定性分析提供基础数据。
It applies angle-changeable-plate shear test and direct shear test in marlite, shale and weak planes of different lithology in the slope of the section K81-K83 of Zhucheng highway in Hunan. Meanwhile, it applies M. Georgi method to weaken and reduce the shear strength of rock and the shear strength of weak planes of rock, which supplies basic data to the further analysis of slope stability .
