探索横波地震的理论误区
|
摘要
由于横波地震的分辨率很高,20世纪80年代中期曾掀起过横波地震热。但因数据采集困难,以及地质解释成果经不起验证等问题而迅速降温。这是由错误的传统横波地震理论造成的。笔者以大量的横波地震工程地质勘察实践和严格的成果验证来说明横波的激发方式与纵波没有本质区别。天然条件下横波的传播速度与纵波传播速度间并不存在数学规律。本文还介绍了笔者在岩溶、第四系沉积勘察等工程项目验证的实例。
Owing to the high resolution of S-wave seism, study of S-wave seism became very popular in the 80’s of the 20 th century, but it was rapidly ignored for the difficulty of collecting data, the geological result that could not be interpreted clearly and so on. In fact, the problems arose from the misunderstandings of traditional S-wave seismic theory. In this paper, the author wants to point out that there is nonessential difference between S-wave and P-wave in stimulating method by means of lots of S-wave geological exploration cases and strict result tests, and furthermore to illustrate there exists no mathematic laws between S-wave velocity and P-wave velocity.
