摘要
本文用红砂岩试件做了一系列的试验,探讨了在多轴压缩下红砂岩的强度和变形特征。重点讨论了中间主应力σ_2对红砂岩强度的影响以及应力—应变曲线和侧压力的关系。此外,对柔性接触的多轴压缩试验也作了初步尝试。
Systematic tests were conducted on specimens of red sandstone under polyaxial compression, and the strength and the deformation characteristics were carefully investigated. The results of tests are reported in this paper, and the effect of intermediate principal stress on the ultimate compression strength is discussed, together with the relationship between stress-strain curves of the rock and the lateral pressure acting on it. Test with flexible contact is also reported.
