摘要
选用不同风化程度的砂岩试件为研究对象,对其单轴、三轴力学强度进行了试验研究。结果表明,随着风化程度的增加,砂岩的力学强度逐渐降低;三轴曲线的主应力差对砂岩强度的影响基本呈线性;不同风化程度的砂岩试件的内摩擦角随着风化程度的增加逐渐增大;粘聚力则随着风化程度的增加而减小。
Both uniaxial and triaxial sandstone strength are studied in different level of weathering. The results show, sandstone strength will reduced as the level of weathering rise; the effect on the strength of sandstone caused by principal stress difference is linear essentially; internal friction angle of sandstone will rise and cohesion will reduced as the level of weathering rise.
