【摘要】 裂隙化岩体由于其间存在着由不连续面构成的复杂网络系统,使其力学行为十分复杂,尤其这种岩体的变形没有规律性,使得对其研究十分困难,分形几何提供了一个解决自然界中不连续、不规则、复杂现象的好办法。本文用分形几何探讨了裂隙化岩体的变形参数与分数维之间的关系,并建立了两者之间的统计回归数学关系。更多还原

【Abstract】 Difficulties have been found in the evaluation of the mechanical property and behavior of fissured rock due to the presence of complex discontinuous network sys tem.The fractal geometry provides a good method to deal with the discontinuous, irregular and complex phenomenon in the nature.The relation between the deformation parameters of the fissured rock mass and the fractal dimension was studied on the site of the Daliushu Dam,and a statistical regression model was constructed which was a complex discontinuity function.With the regression equation in rock mechanical modelling,the nonlinear mechanical behavior of rock mass can be well discribed.更多还原
