| 摘 要： | 提出了控制地震概念和用时间反转方法实现非均匀地壳中波的聚焦，从而实现动力触发地震的思路。采用了有限元动力学仿真技术，研究了在波的遍历模型、线性不均匀的介质、以至非线性介质中的时间反转，探讨了在潜在震源区域人工聚能的可能性。结果表明这种聚能是可行的，在考虑介质非线性的条件下，波能量至少可以近似地聚焦。

| Abstract: | A new concept of earthquake occurrence control,and a consideration of using the time reversal method to realize the focusing wave energy in earth crust and triggering earthquake dynamically,are proposed.In the method the technology of ND-FEM emulation is adapted to study the time reversal of wave in un-even,and further more non-linear crustal media,verify the feasibility that focus seismic wave energy on to the potential epicentre.The result shows that it is feasible to focus the wave energy through crust ,at least an approximate focus through non-linear crustal media. |
