项目摘要

By performing parametric study with different magnitude and distribution of stress drop, yield stress and initial stress along the fault, and the magnitude of mesh size of the finite element models, we could obtain the following outcomes.(1) There was a linear relationship between the average dislocation and the average stress drop irrespective of the magnitudes of initial stress and yield stress.(2) The average rupture velocity depended on the difference between the yield stress and the initial stress. The larger the difference, the smaller the average rupture velocity. When the difference was small, the rupture velocity exceeded the S-wave velocity, but not the P-wave velocity.(3) The frequency characteristics of simulated ground motion by the proposed method strongly depended on the mesh size of the finite element model. There was the cut-off frequency depended on the body wave velocities and length of the finite element mesh. The cut-off frequency closely resembled the Nyquist frequency when the length of the element is equal to half of the corresponding wave length..The simulated ground motions, such as accelerations, velocities and displacements for the 1994 Northridge earthquake had similar magnitude of amplitudes and frequency characteristics in low frequency range to the recorded ground motions, which implies the validity of the proposed method.
通过对不同应力降、屈服应力、初始应力沿断层沿着的大小和分布以及有限元模型的网格尺寸大小进行参数研究,得到以下结果。(1)平均位错与平均应力降之间存在线性关系,与初始应力和屈服应力的大小无关。(2)平均破裂速度取决于屈服应力与初始应力之差。差异越大,平均破裂速度越小。当差异较小时,破裂速度超过横波速度,但不超过纵波速度。(3)该方法模拟的地震动频率特性强烈依赖于有限元模型的网格尺寸。存在与体波速度和有限元网格长度有关的截止频率。当元件的长度等于相应波长的一半时,截止频率非常类似于奈奎斯特频率。对1994年北岭地震的加速度、速度和位移等地震动的模拟结果表明,在低频范围内,模拟结果的幅值和频率特性与实测结果基本一致,表明了该方法的有效性。
