断弯褶皱正演模拟

断弯褶皱是挤压盆地中一种重要的构造模型。其形成原理是：在断层开始滑动时，形成一个膝折带，随着断层的继续滑动，膝折带不断增宽，形成单处台阶断弯褶皱。在平行条件的假设下，可以推导出单步台阶断弯褶皱各要素间的数学关系式，由此写出流程图，编写断弯褶皱的正演模拟的计算机程序，进而对挤压盆地的单步台阶断弯褶皱进行计算机模拟，并给出其模拟结果图。

The Forward Simulation of the Fault- Bending Fold

Fault-beding fold is an important kind of structural model.The principle of formation is that as soon as the fault slip,the kind band is forming.With the sliping,the kind band is increasing and the simple ramp of fault-bending fold is developing.In the condiction of parallel behavior, the mathematical relationshipof a simple ramp fault-bending fold can be made,so does the flowingchart.Then the forward modeling program is redacted.Moreover ,a simple ramp fault-bending fold in compressed basin is analogyed and the result of fault-beding fold analogy is showed.
