摘要将水利工程中的渗流有限元法应用于模拟研究松散含水层对工作面的充水影响，既考虑了松散含水层的富水性、水头，又考虑了采动影响对覆岩的破坏，继而引起的渗流通道的变化。 - The paper analyzes the chaos characteristics of the rock stress ^ fragment dimension crashing process under the explosive blasting by the chaos theory for the first time , puts forward academic point of view that blasting system is a typical chaos system , adding up to damage mechanics , reduces the connection between blasting fragment face and original damages of rock . then , the concepts of blasting attracted face and the blasting attracted factor have been put forward
结合损伤力学研究了爆破破碎面与岩石初始损伤的关系，首次提出了爆破吸引面、破碎吸引因子的概念；结合分形理论，讨论了爆破吸引面分形维数与破碎块度分形维数之间的关系；使岩石在爆破作用下的本构关系研究转化为破碎吸引面的本构关系研究。 - In order to study the influence of evolvement of permeation character induced by mesoscopic structural characteristics on macroscopic mechanical behavior and fracture mechanism , a nonlinear constitutive equations describing the relationship between damage of rock and seepage is proposed based on mesoscopic damage mechanics and biot seepage mechanics theory and coupling system of flow & solid in rock failure process analysis , f - rfpa2d , is developed to simulate the variation of permeability as well as coupling mechanism between seepage and stress during the initiation , propagation and coalescence of cracks in rock . this study also extends the research field of original rfpa2d
为了分析细观结构特性变化引起渗透性演化对宏观力学行为的影响,并进行渗流应力耦合作用下岩石破裂机制的研究,本文基于细观损伤力学和biot经典渗流力学,建立了岩体损伤非线性本构方程和渗透率关系模型,开发出岩石破裂过程渗流-应力耦合分析系统( couplingsystemofflow & solidinrockfailureprocessanalysis简称f - rfpa2d ) ,拓宽了原有程序rfpa2d的研究领域。
