广东省新丰江水库地区1962年3月19日发生 M_s=6.1的地震.地震前后,库坝区分别布设了水准测量网和三角测量网.形变测量具有精度高、测期密的特点.本文通过对不动点的处理,得出新的形变场并讨论了它的特点;根据各相邻期的三角测量结果计算了各三角形的主应变;依据地震时的应变对一次5.3级的地震的发震断层作了反演.结果表明,地壳水平形变与新丰江水库地区4级以上地震有明显的关系,垂直形变与这些地震无明显关系. An earthquake of M_s = 6.1 occurred on March 19, 1962, in Xinfengjiang Reservoir Area, Guangdong Province, China. Before and after the earthquake, a leveling network and a triangulation network were laid out respectively. The deformation measurement has the characteristics of high accuracy and tight measuring period. Through the processing of the fixed point, a new deformation field is obtained and its characteristics are discussed. Based on the triangulation results of each adjacent period, the principal strain of each triangle is calculated. According to the earthquake strain, a 5.3-grade earthquake The results show that the horizontal crustal deformation is obviously related to the earthquakes above the 4th magnitude in the Xinfengjiang reservoir area, and the vertical deformation has no obvious relationship with these earthquakes.
