【摘要】 通过使用"LGADJ"软件,分析范县地震前后的重力场变化特征发现:震中附近的重力点值在地震的孕育—发震—震后调整阶段,出现了下降—上升—下降的过程。从重力变化的角度,我们认为,该地震前后的重力变化支持孕震过程的膨胀理论;指出:通过加强观测研究冀鲁豫交界地区重力场变化,不断探索地震破坏机理,为和谐新农村建设提供地震安全保障!更多还原

【Abstract】 With the software "LGADJ",the variation feature of gravity field before and after the Fan county earthquake is analyzed.The result shows that the variation of gravity value in the station near epicenter represents as a raising-dropping-raising process during the pregnancy,occurrence and aftershock adjustment stages of the earthquake.From the view of gravity field variation,we think that the gravity variation going with this earthquake supports the inflation theory of earthquake gestation process;By strengthening the study on gravitational field change in joint region of Hebei,Shandong and Henan Province,exploring earthquake destroying mechanism,better earthquake safety control for the harmonious new rural reconstruction can be provided.更多还原
