Much remains to be understood about how small faults grow into large faults and how the propagate through the crust. Such knowledge has considerable significance for evaluation of seismic hazards and the exploration for petroleum. This study will address this issue through the construction and refinement of computer programs which simulate faulting and the growth of folds related to the faults. Two different approaches will be utilized and the combination of these should reveal aspects of the phenomenon which have not yet been determined. A limited set of field examples will be studied to determine the extent to which computer models produce realistic results.

关于小断层是如何发展成大断层的，以及这些断层是如何在地壳中传播的，还有许多问题有待于了解。这些认识对地震灾害性评价和油气勘探具有重要意义。本研究将通过构建和改进计算机程序来模拟断层作用和与断层相关的褶皱的生长来解决这个问题。将采用两种不同的方法，这两种方法的结合应能揭示尚未确定的现象的各个方面。将研究一组有限的现场实例，以确定计算机模型产生逼真结果的程度。
