摘要
利用山西断裂带布设的GPS监测网的6期复测资料(1996—2001),分析了山西断陷带的水平运动特征。结果表明,整体呈现逆时针的差异活动,主压应力场的方位角为72°,断裂两侧不存在明显的走滑运动。2001年的运动显示,代县附近是差异活动的分界区段。
An Analysis of horizontal movement characteristics of Shanxi fault belt is made by using 6 retest data of 6 periods(1996-2001) of GPS monitoring network in Shanxi fault belt.The result shows that whole differential movement is counterclockwise, with a principal compressive stress azimuth of 72°.There is no obvious strike slip movement along two sides of the fault.The movement of 2001 shows that the area around Dai county is the boundary area for differential movement.
