| 摘 要： | 影响岩石抗压强度试验值的因素很多,这些因素大致可分为两个方面:一方面是岩石自身的因素,如矿物成分、结晶程度、风化程度等;另一方面是试验方法上的因素,如试件形状、尺寸大小等。研究结合西南某水电工程勘测设计工作需要,进行了4种不同尺寸的岩石单轴抗压强度比较试验,以探索岩石单轴抗压强度的尺寸效应。试验研究结果表明:岩石单轴抗压强度的尺寸效应明显,随试件尺寸的增大,其抗压强度值逐渐减小。

| Abstract: | There are many factors influencing rock compressive strength,including two kinds of them :first,rocks themselves,such as composition of mineral,crystal degree,weathering level and so on;second,test methods,such as specimen shape,size and so on.In this study,combined with one hydropower project investigation and design works in southwest China,uniaxial compressive strength tests for rocks with 4 different sizes were carried out to study scale effect of rock uniaxial compressive strength.The experiment study ... |
