本文应用形变破裂和激光全息光弹实验,结合断裂力学的观点研究了地震破裂过程的三个方面:1.地震破裂的力学机制;2.地震破裂的应变特征与运动过程;3.地震破裂过程的应力场分布特征。并分析了地震破裂过程的几何学与运动学特征以及探讨了它们与地震发生。前兆和余震迁移的密切关系。此项研究为活动断层分段研究和地震预报提供了实验证据。
In this paper, deformation rupture and laser holographic photoelastic experiment, combined with the fracture mechanics point of view of the three aspects of the earthquake rupture process: 1. Mechanics of earthquake rupture; 2. Strain characteristics and movement process of earthquake rupture; 3. Stress field distribution during earthquake rupture. The geometrical and kinematic characteristics of the earthquake rupture process are analyzed and their occurrence and earthquake occurrence are discussed. The close relationship between precursor and aftershock migration. This study provides experimental evidence for active fault segmentation and earthquake prediction.
