浅层地震多波勘探新技术研究

Research on the New Exploration Technique of Multiwave for Shallow Earthquake

针对工程地震勘探中点震源激发的波列 ,应用τ -P变换等多种技术 ,对波列中的反射纵波、折射纵波以及瑞雷波进行分离、识别与提取。试验及实测资料表明 ,该方法技术可用于上述 3种波的联合勘探 。

The reflection longitudinal wave, refraction longitudinal wave and Rayleigh wave in the wave train are separated, distinguished and drawn by using the technique of τ-P conversion for the wave train excited by point seismic focus in engineering seismic exploration. Indicated by test and measured information the said technique may be used both for the combined exploration of the 3 kinds of wave mentioned above and for single wave exploration.
