| 摘 要： | 地下流体对地震的孕育、发生过程起着重要作用.本文简述了近年来国内外关于地下流体影响地震的研究进展,对流体诱发地震的物理机制进行了深入介绍,主要有孔隙压的增加对有效应力的降低、流体受热膨胀扩容以及对岩石的润滑和软化作用；同时介绍了一些典型的流体触发地震模式,包括地震泵、断层阀、膨胀—扩散模式等,并讨论了目前存在的主要问题...

| Abstract: | Underground fluid plays an important role in the earthquake preparation and occurrence.This paper reviews the research results about impact of underground fluid on earthquakes,and mainly introduces the physical mechanisms of fluid-induced earthquakes,such as increasing in pore pressure,fluid expansion due to thermal effect and softening effect of rock.Also it introduces some typical models of fluid-induced-earthquakes including earthquake pump,fault-valve,dilation-diffusion mode.Finally existing problems are pointed out and works need doing in the future is suggested.These results provide us new angles of view for further research of earthquake prediction and interaction between fluid and earthquakes. |
