摘要
根据第一作者多年来从事用断裂动力学的解析解来表示强震地面运动的振幅、速度、加速度 ,所得的结果与两次著名强震地面运动的记录进行了比较 ,二者符合较好 ,故提出应用断裂动力学的研究成果来制定确定性的地震烈度区划方法的初步探讨意见。
Based on the study for many years for the analytical solutions of different modes of fracture dynamics, the first author of this paper used his results to draw the curves of variation to the amplitudes, velocities and accelerations of different points It needs the tip of a rupturing fault to compare with the records of Taft earthquake on July 7, 1952 (horizontal ground motion), and Coalinga aftershock on May 8, 1983 (vertical ground motion) Our calculated results coincide these two seismic records well, we give our primitive suggestion how to apply fracture dynamics to define the seismic intensity zoning
