一、鲜水河断裂带上的形变监测系统自1973年炉霍大震以后,在鲜水河断裂带正式开展地形变测量工作。我们在该断裂带及其两侧约4万平方公里的地区内,完成了4334公里的精密水准测量,布设了13处大、中、小型测边、测角网和12处跨断层短基线、短水准场地;建立了定点形变观测站,从而形成了由点到面、初具规模的形变监测系统。 First, the deformation monitoring system on the Xianshuihe fault zone Since 1973, after the Huohuo earthquake, the deformation measurement of the Xianshuihe fault zone has been formally carried out. We completed 4,334 kilometers of precision leveling in the area of ​​about 40,000 square kilometers on both sides of the fault zone and in 13 large, medium and small measuring edges, goniometers and 12 short-span straddling faults. Short standard field; set point deformation observation station, thus forming a point to surface, beginning to take shape of the deformation monitoring system.
