论文摘要
我们提出了一种新的方法，可以将裂缝的可变应力变化从内部地面位移中变化。断裂可以是断层或岩浆入侵，嵌入了具有突出地形的3D异质地壳中。该方法基于使用XFEM类型的有限元离散化的虚拟域方法。成本函数涉及物理问题解决方案与观察到的数据以及平滑项之间的不合适。正则化参数是通过使用L曲面确定的。然后，将该方法重新构建，以应用于地球卫星方向的InsAR数据（掩盖和嘈杂）。合成测试证实了我们方法的效率和有效性。
We present a new method to invert variable stress changes of fractures from InSAR ground displacements. Fractures can be either faults or magma intrusions, embeded in a 3D heterogeneous crust with prominent topographies. The method is based on a fictituous domain approach using a finite element discretization of XFEM type. A cost function involves the misfit between the solution of the physical problem and the observed data together with the smoothing terms. Regularization parameters are determined by using L-curves. The method is then reformulated to be applied to InSAR data (masked and noisy), projected in Earth-Satellite directions. Synthetic tests confirm the efficiency and effectiveness of our method.
