摘　　要：在复杂地表条件的地区 ,如沼泽、丘陵、沙漠、戈壁滩及山前破碎带 ,因地表起伏和表层结构横向变化大 ,反射波传播路径发生畸变 ,而造成时距曲线畸变 ,无法很好成像 ,笔者根据理论研究和实际处理过程 ,总结了一套适合复杂地表条件的初至模型静校正、扩大面元组合静校正和相关法自动剩余静校正循环迭代的处理方法。通过实际处理 。In rugged near surface area, undulating ground and lateral variation in surface structure can distort the propagation path of reflection, cause the distortion of time distance curve and hence lead to poor image. With the purpose of solving these problems, the authors, based on theoretical study and practical data processing, have developed a new series of static correction methods, which include first arrival statics, enlarging bin statics and correlation automatic residual statics. Case studies show the good effect of the methods.
