| 摘 要： | 利用含超压气体裂隙震源模式［１］分析研究了Ｐ波初动符号的分布．根据理论推导，不同倾角含超压气体裂隙可分别形成Ｐ波初动符号的四象限分布图象和圆、椭圆、抛物线、双曲线等圆锥曲线形Ｐ波节线．按节线形状和失稳方式进行了地震分类．所推论的初动Ｐ波、Ｓ波振幅分布规律和地形变特征都与实际相符

| Abstract: | By using the seismic source model of crack containing hyperpressure gas ,the distribution of the first motion mark of P wave is studied.According to the deduction,the cracks containing hyperpressure gas with different inclination can form the distribution pattern in four quadrants of first motion mark of P wave and the nodal lines of P wave in the shape of conic section,such as circle,ellipse,parabola and double curve etc..According to the shape of nodal lines of P wave and type of instability,the earthquakes are classified.The distribution feature of first motion amplitude of P and S waves and the feature of ground deformation etc.deduced correspond with practice. |
