约束层析静校正方法应用效果分析
|
摘要
折射静校正方法的假设前提决定了其在表层结构复杂地区的应用效果欠佳,约束层析静校正方法能够适应低降速带速度的纵横向变化和近地表成层性差等复杂条件。在简要分析折射静校正方法对复杂近地表结构地区不适应性的基础上,阐述了约束层析静校正技术的基本原理及其实现步骤;给出了约束层析静校正技术在西部近地表结构复杂地区的应用结果,对比了层析反演时有无约束条件下的近地表建模精度与静校正效果差异,表明约束层析静校正技术在解决复杂近地表结构地区静校正时具有明显的技术优势。
The assumption of refraction static correction indicates that it cannot be applied in the area with complex surface structures.On the contrary,constrained tomographic static correction is suitable for the lateral and vertical variation of the velocity of weathering layer,as well as the poor layering of near surface.After briefly analyzing the inadaptability of refraction static correction in the area with complex near-surface structures,the basic principles and steps of constrained tomography static correction was described.Then the constrained tomography static correction was applied in the western area with complex near-surface structures.In addition,the difference of near-surface velocity modeling and static correction by tomography inversion with and without constrained conditions,and the constrained tomography static correction shows obvious advantage in complex near-surface area.
