该文以弱各向异性准P波速度表达式建立地震波传播走时与弹性系数的线性关系,基于惠更斯原理计算准P波射线传播;由数据残差项与模型正则项来形成目标函数,并以共轭梯度求其I2范数解;从而实现了各向异性介质中地震波射线迭代层折反演方法,并应用于数值计算和实测资料处理中,效果良好.“,”This paper formulates the linear relationship between seismic traveltime and elastic coefficients using the expression of weak anisotropic P-wave slowness; calculates qp wave ray propagation based on Huygens' principle; adopts CG algorithm to obtain l2 solution of an objective function which is built up from a linear combination of the data misfit and regularizatio terms; and efficiently performed the iterative ray tracing tomography in anisotropic media. The tomographic method is applied to the synthetic and field P-wave data.
