摘要
应力与渗流耦合作用下岩体的变形和破坏特征,与岩体结构、岩体的力学性质、渗流场有关,结合边坡的稳定分析模型,研究合理分析计算岩体的力学参数、渗透系数张量的方法。利用岩体质量分类系统和塑性破坏准则估算裂隙岩体的力学参数,计算裂隙岩体的渗流系数,为岩体稳定分析奠定基础。
In the stress and seepage coupling , deformablity ＆ disruption characteristics of rock mass have a part in rock structure, mechanics nature and seepage fields. By combining analysis model of the rock slope stabili- ty, reasonable analysis ＆ computer methods of the rock＇s mechanics parameters and the tensor of permeability coef- ficient are studied. The fractured rock mechanics parameters is estimated by rock mass quality classification system and plasticity failure criterion, and computed the permeability coefficient of the fractured rock. It lais a foundation for analysis of the rock stability.
