摘要
列车振动具有重复性高、能量强、能穿透地下介质并有效传播等特点。本次试验布设浅层地震仪记录列车振动产生的地震波,从中提取出有效的瑞雷面波成分,并成功反演出观测位置的地下地层结构,反演结果与真实地层结构相吻合,这充分说明列车振动面波方法可以用于地下结构勘探。在铁路沿线,尤其城市及交通拥挤地区,列车振动可作为一种有效利用、绿色环保的新型震源来探测地下地层结构,是对传统地震勘探震源受限条件下的一种可行解决方案。
It has been found that the vibration induced by trains has characteristics of repeatability, high energy and transmissibility in the ground. Through disposition the shallow seismographs, the signal or data record was gotten and the Rayleigh wave was abstracted. Conclusion has been made that the Rayleigh wave can be used in underground exploration, and the underground structure involving the Rayleigh wave was agreed with the historic result. The vibration induced by trains will be a new type of green source of seismic exploration along the railway , especially in cities and rush congested areas . Also it will be a substitute when the condition of the traditional exploration methods are restricted.
