| 摘 要： | 采用SAM方法对重庆市荣昌台2000～2006年（缺2001年资料）的数字地震资料进行S波分裂的计算分析，并讨论了其与该区构造的关系。计算结果表明，S波快波偏振方向主要集中分布在NW向40°～45°、75°～85°。认为S波快波优势分布方向为NW向，与荣昌地区所受区域应力场方向大致一致，与该区的主要基底断裂走向接近垂直，反映了该区应力场的大致轮廓，为地震预报提供信息。 |
| 关 键 词： | 荣昌 S波分裂 区域应力场 |

| Abstract: | Using SAM method to compute shear wave splitting of digital seismic datum from 2000 to 2006 recorded by Rongchang station, Chongqing, and disscussing the relation between the result and structure. The result shows, most polarization directions of fast wave of shear wave are N40° -45°W,N75°-85°W. The predominant polarization direction is consistent with stress field direction of Rongchang region, but it is vertical to basement fault strike in the region, this reflect stress field in the region, and this can provide information for earthquake prediction. |
| Keywords: | Rongchang Shear wave splitting Regional stress field |
