【摘要】 研究岩土材料形成过程中其化学、物理、力学性质的演化规律及岩土材料在应力作用下,其裂隙分布分维、破裂点及声发射空间分维、裂纹扩展或断裂表面生成分维、孔隙壁生长分维、颗粒破碎分维等一系列能用分形几何来描述的现象随时间的动态演化规律,进而揭示岩土材料受力变形过程中的应力状态、力学性能、物理和化学性质的演化与分维值的相关关系, 从而初步建立岩土材料的分形动力学理论框架,简述了分形动力学理论的工程应用。更多还原

【Abstract】 In investigation of involution laws of geotechnical material in chemical, physical and mechanics property, the phenomenon of the distribution of cracks damage,points and acoustic emission, expansion of cracks, appearance of surface of cracks, development of holes, appearance of fragmentation appear fractal character. Studying the dynamic evolvement laws of these phenomenon’s fractal dimension value, can discover the relation between the fractal dimension value and the stress state, mechanics capability, physical and chemical characters, constituting theory frame of fractal dynamics of geotechnical material, and apply in practice.更多还原
