新第三系红层不同含水量与其力学性质关系试验研究

通过对黄河上游山间盆地新第三系红层岩石含水量进行现场观测，得出了红层不同状态含水量的变化规律。进而开展不同含水量下的岩石（体）单轴、三轴抗压、原位载荷、抗剪、变形等试验，得出了岩石（体）变形破坏与含水量之间的关系，确定了红层岩体物理力学参数取值原则，给出了红层合适的物理力学参数建议值。

On Relation Between Different Water Contents and Mechanical Properties of Neogene Red Stratum

Based upon the field observation of the Neogene red rock stratum in the intermountainous basin of the Upper Yellow River, the variation law of water contents was achieved under different conditions of rock stratum, Then a series of rock tests, such as uniaxial compressive strength test, triaxial test, in situ load test, shear test and deformation test, had been performed under different water contents. The relation between rock deformation failure and water content was obtained. It puts forward the principle to determine physical and mechanical parameters of red rock stratum, and presents its proper physical and mechanical parameters.
