| 摘 要： | 以程潮铁矿为工程背景,为获得不同岩性矿岩的基本力学参数及分形维数,进行了直剪实验及粗糙度扫描实验。分析水和充填物对节理面剪切强度的影响,并综合考虑岩石节理面粗糙性对其力学性质的影响,建立了体现相同法向应力下峰值剪切强度与分形维数的关系公式,为更深入研究岩体稳定性及破坏机理提供了可靠的矿岩力学参数及依据。

| Abstract: | With Chengchao Iron Mine as the engineering background,for obtaining the basic mechanics parameter and fractal dimension of different rocks,the direct shear test and roughness scanning tests on them were made.The affection of water and fillings to the joint plane shear strength of rocks was analyzed.The relational formula of peak shear strength and the fractal dimension under the same normal stress was established,in which the influence of the surface roughness of rock joints to the mechanics property was c... |
