本研究是为了验证和认识断层破裂过程中涉及断层分离的地震断层界面波现象。基于Schallamach和Comninou- Dundurs的早期工作，以及用泡沫橡胶和聚碳酸酯固体模型进行的实验室断层破裂实验，进一步的建模将与有限差分计算一起进行。如果得到证实，这项工作将涉及沿断层的低热流、沿断层的弱应力、大逆冲和破裂的锁滑脉冲模型等问题。这项研究是国家减少地震危害计划的一个组成部分。
英文摘要
This research is to verify and understand the phenomenon of earthquake fault interface waves involving separation of the fault during rupture. Based on earlier work by Schallamach and Comninou- Dundurs, and on laboratory fault-rupture experiments with foam rubber and polycarbonate-solid models, further modeling will be done along with finite difference calculations. If confirmed, the work bears on questions of low heat flow along faults, weak stress along faults, large overthrusts, and the locking-slip pulse model of rupture. This research is a component of the National Earthquake Hazard Reduction Program.
