摘　　要：在野外复杂山地区,地表起伏大,岩石时常露出地表,低降速带速度与厚度横向变化剧烈,近地表结构复杂,利用表层调查模型和初至折射静校正方法不能很好地解决静校正问题。层析静校正方法不受近地表结构影响,可以有效解决复杂山地区静校正问题,但是在野外三维采集中,层析静校正计算太耗时,效率极低。因此,本文提出一种三维快速层析静校正方法,不仅能够保证静校正效果,而且能够大幅提高效率。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.Therefore,a three-dimensional fast chromatographic statics method is proposed in this paper,which can not only guarantee the statics effect,but also greatly improve the efficiency.
