Introduction Finite element method has a wide application in analyzing the crust tectonic stress field and tectonic deformation field. WANG, et al (1980), for example, reversed the crust stress field and forecast future seismic risky area using finite element way. WANG and CHEN (1980) made the numerical simulation on modern tectonic stress field for China and its adjacent area using finite element and obtained the whole picture of tectonic stress filed in China. Except analyzing the tect… 相似文献

Considering the heterogeneity of geomechanical materials, seismicity during brittle rock failure under compressive loading
on the sample with an original weak zone is simulated by using rock failure process analysis code (RFPA2d
). The run-through process of weak zone, the forming of new fault and associated micro-seismicities are studied. The modeling
demonstrates the total process of source development of earthquake from deformation, micro-failure to collapse and the behavior
of temporal-spatial distribution of micro-seismicities. The stress, strain and the temporal-spatial distribution of micro-seismicities
life-likely portrayed the phenomena of localization and temporal-spatial transitions, which is similar to those observed in
our real crust. Also, the results obtained in simulations are in agreement with or similar to the reported experimental observations.
