摘要
针对岩石中裂纹分布的非均匀性，作者提出了二维和三维空间中的滤过的油松点场用于描述裂纹场的统计特性，并引入有效场方法分析岩石细观损伤的本构关系．该方法既能分析均质岩石的裂纹相互作用，又能分析非均质岩石的裂纹相互作用；不但适用于拉伸裂纹的相互作用，而且也适用于压缩荷载作用下的裂纹相互作用．
The two. and three-dimensional filtered Poisson point field theory is proceed to study the damage characteristics for statistically inhomogcneous rocks with randomly distributed cracks. The ef-fective field mothed is employed to analyze the micromechanical damage constitutive relations. Therefore, the statisticany effective field method can analyze the interaction among cracks not only for homogencous or inhomogencous rocks but also for tensive or comprasive loadings.
