摘要

采用相同直径不同高度的圆柱形白色大理岩及灰岩试样进行单轴压缩试验研究，验证了脆性岩石抗压强度在一定范围内随高径比的增大而减小的规律。依据岩石单轴压缩试验结果，基于灰色预测GM（1，1）模型建立了脆性岩石的单轴抗压强度与试件高径比之间的非线形关系式，该经验公式对脆性岩石具有统一的形式，同时通过式中参数a值反映了由于岩性、试验条件等不同而引起的强度差异。利用该关系式可以很方便地在相关岩土工程中为相似岩石估算其强度值提供参考、借鉴。

Abstract

For white marble and limestone specimens of same diameters and different heights

uniaxial compression strength tests are carried out. The regularity that compression strength of brittle rock reduces with the increase of height–to-diameter ratio is certified. Based on the results of compression strength tests and the grey model GM(1

the nonlinear equations between uniaxial compression strength and the height–to-diameter ratios of specimens are worked out. This empirical formula for brittle rock is uniform

and the difference of rock strengths with different rock characters and test conditions is reflected by a parameterα. Fortunately

the equations are very convenient to provide consultation and reference for evaluating the strength of the similar rock in the related engineerings.
