Method and application of three-dimensional fast chro-matographic statics calculation for complex mountainous terrain
In the field of complex mountain areas,the surface fluctuation is large,the rocks are often exposed to the surface,the lateral changes of velocity and thickness in the low-velocity zone are drastic,and the near-surface structure is complex.The statics problem cannot be solved well by using the surface investigation model and the first refraction statics method.The chromatographic statics method is not affected by the near-surface structure and can effectively solve the problem of statics in complex mountain areas,but in the field of three-dimensional acquisition,the chromatographic statics calculation is too time-consuming and the efficiency is very low.There-fore,a three-dimensional fast chromatographic statics method is proposed in this paper,which can not only guar-antee the statics effect,but also greatly improve the efficiency.
