浅层三维横波地震勘探方法研究

The research on shallow three-dimensional transverse wave method of seismic exploration

通过对横波传播规律及运动形式的数学模型、物理模型及实测数据的研究 ,发现横波与纵波一样具有三维波场的特性 ,利用横波的这一特点就可以进行三维横波的野外观测。经大量实际资料表明 ,利用三维横波资料可以解释埋于地下 5～ 40 m深度范围内的空洞及古巷道 。

Through the research on mathematical model,physical model and real data of the dissemination rule and motion form of transverse wave,it is founded that transverse wave has the same characteristic in three dimensional wave field of longitudinal wave.In the light of this feature,field observation on three dimensional transverse wave can be done.A great deal of practical data show that,using the data of three dimensional transverse wave can explain the cavity and ancient lane,buried at the depth of 5～40 m and can stratify precisely the layers simultaneously.
