摘要
推导出向、背型地质界面上的折射波时距曲线方程。此曲线形态与水平、倾斜、直立界面上的时距曲线相似。因此,折射波时距曲线反演具有多解性,利用追逐和相遇时距曲线观测系统获得实测数据,结合广义互换时法中的速度分析判断界面形态,可以减小或消除多解性。对比了t0法与广义互换时的优缺点,并举例说明广义互换时法可更详细地确定界面形态。
Forward modeling of refraction over synform or antiform interfaces is developed with ray-tracign techniques. The ambiguity of refraction time-destance curves is pointed out. The forward and reversed profile and offset profele in field work and velocity analysis in data interpretation are suggested. It is pointCd for subsurfale topography interfaces ly using the Generaliged Reciprocal Method.
