The findings indicate that under uniaxial compression, the red sandstones at first experience structural intensification and then structural degradation until they are failed; the unconfined compressive strength of red sandstone is mainly related with compaction rate, pore distribution and connecting condition of mineral grains; and the above factors have a more notable impact on the unconfined compressive strength of red sandstone with the increase of weathering; with the increase of load, the grains area ratio and Euler number decrease, the pore develops towards centralization or collectivization, and the red sandstones gradually lose their resistance to deformation.

研究结果表明：在单轴压缩条件下，红砂岩先结构强化，后结构劣化，直至最终破坏；红砂岩的单轴抗压强度主要与密实程度、微孔洞等缺陷的分布情况及矿物颗粒之间的联结状态有关，随着红砂岩风化程度的增强，以上各因素对其单轴抗压强度的影响将更加显著；伴随荷载的增加，红砂岩的矿物颗粒面积比例及欧拉数总体上趋于减小，孔隙向着集中化和集团化的趋势发展，红砂岩抗变形能力逐步丧失。
