南宁电厂白垩系碎屑岩的强度和变形特征研究

Study on strength and deformation characteristics of cretaceous clastic rocks at Nanning plant

对国电南宁电厂新建工程场地白垩系下统上组(KC1)的泥质粉砂岩、含砾中至粗砂岩及砾岩的单轴抗压强度和变形破坏特征进行了较为详细研究,结果表明:三种碎屑岩的单轴抗压强度受岩石含水量的影响很大,天然状态下,泥质粉砂岩的单轴抗压强度最小,含砾中至粗砂岩与砾岩的差异不大,但三类岩石单轴抗压强度受含水量影响的敏感程度存在显著差异。

To study axial compressive strength and deformation characteristics of muddy siltstone,pebbly medium-coarse sandstone and conglomerate rock at the upper of lower cretaceous（ KC1） in the Nanning plant site of China State Power Corporation in detail,the result show that： the water content of rock greatly affected axial compressive strength of three kind of clastic rocks,under the natural state,the axial compressive strength of muddy siltstone is minimum,that of pebbly medium to coarse sandstone and conglomerate have small differences,and there are significant differences in the sensitivity of axial compressive strength of three types of rocks affected by water content.
