地震折射波数值模拟

Numerical simulation of seismic refraction wave

折射波法是一种有效的地震勘探方法,在工程地质、水文地质、油气勘探及探查地球深部构造等方面有重要应用。本文在折射波正演模拟方面采用射径法和逐段迭代射线追踪法进行折射波正演模拟,采用射径法进行了针对多层倾斜界面的折射波运动学反演模拟。数值模拟计算速度快,反演精度高。

Seismic refraction method is an effective seismic exploration method.It is widely used in the fields of engineering geology,hydrogeology,petroleum exploration and it also help detect the inner structure of the earth.The paper uses ray method and iteration step by step method for the forward modeling and ray method for reverse modeling.Numerical simulation computer fast and has high resolution.
