层析成像技术被公认是解决复杂近地表地区静校正问题最具希望和潜力的技术 ,它突破了常规折射波解释算法层状介质假设的限制 ,适合于地形起伏大 ,速度横向变化剧烈 ,甚至有基岩出露的复杂地区。此次 ,吐哈胜北 3Ｄ用作试验的三束线 ,地形起伏很小 ,野外静校正量的变化范围小于 Tomography is recognized as the most promising and potential technique to solve the problem of static correction in complex near-surface regions. It breaks through the limitations of the layered media assumptions of the conventional refractive-wave interpretation algorithm and is suitable for large topographic fluctuations, dramatic changes in velocity and lateral A complex area with bedrock exposed. This time, Tuha Sheng-North 3D as the test of the three beam lines, terrain ups and downs is small, field static correction range of less than
