地震数值模拟（国外英文资料） Seismic numerical simulation of 1.1 Seismic numerical simulation is an important foundation for seismic exploration and seismology. The so-called seismic numerical modeling is the assumption that the underground medium under the condition of known structure model and the corresponding physical parameters, simulation studies the propagation rules of seismic waves in the ground all sorts of medium, and calculation on the ground or underground each observation point should be observed by the numerical seismic record an earthquake simulation method. The seismic numerical simulation method has been widely used in seismic exploration and natural seismic field. It is not only in the oil, natural gas, coal, metal and non-metallic mineral resources and widespread application in the engineering and environmental geophysical, and in earthquake prediction, seismic zone and tectonic and divided into the earths interior structure study, also get quite a wide range of applications. Seismic numerical simulation plays an important role in seismic exploration and seismology. In seismic data collection design, the seismic numerical simulation can be used for the design and evaluation of the field seismic observation system and the optimization of seismic observation system. In seismic data processing, seismic numerical simulation can test the correctness of various inversion methods. In the interpretation of seismic data processing results, seismic numerical simulation can test the correctness of the interpretation results. Seismic numerical simulation and physical simulation of the earthquake belongs to the seismic forward modeling, namely the known underground medium model, structure and physical parameters predicted by the observation point on the ground or in well should be observed seismic record. And the purpose of seismic exploration is based on the ground or well seismic record of each observation point in the observation of underground medium structure model, a
