In the last decade, great advances have been made on the numerical simulation of the orogenic dynamics. Not only an integrated theory has been built up, but also many convincing results were obtained from the concrete example analysis. The quantitative study of the orogenic dynamics has been a hot research point of the continental deformation. In the quantitative study of the orogenic dynamics a series of control equations need to be solved by means of the numerical technique. The results will provide the image of the orogenic dynamic evolution. This makes it possible to understand the role of different factors in the orogenic process and to identify the acceptability of an orogenic model from the mechanical analysis. The investigation of the orogenic evolution requires an equation system integrated from the solid-mechanics and fluid-mechanics as well as the thermodynamics. The intensive largedisplacement and large-strain taking place in the orogenic evolution make the numerical simulation more complicated. The re-meshing technique becomes necessary in this case. The criterion of rock failure and inner boundary condition need to be considered carefully while processing the fault growth, movement and deformation. In addition, the surface erosion and sediment as well as the isostatic compensation must be considered comprehensively in the orogenic simulation.
