横波地震勘查技术在长春市活断层探测中的应用
|
摘要
以解决长春市区活断层的浅层地质问题为前提,阐述了活断层概念和横波的物理特征;从理论和实验的角度分析横波的分辨率和观测系统参数选取的原则.在试验的基础上,确定横波的观测系统,给出研究区的波组特征、断层分布和第四系的埋深情况.
Basing on the geologic problem of shallow active fault,the paper expounded the concept of active faults and characteristics of shear wave.From theories analysis and experiments,the principles of the resolution of shear wave and parameters selection of observation system are obtained.This paper determined observation system of shear wave,wave group characteristics,faults and quaternary on the basis of experiments.
