本文研究了断裂以匀变速扩展时的矩形断层所辐射的远场位移。求出了谱Fcm(ω),以及给出了位移因子 f_cm(t) 的解析表达式井指出 f_cm(t) 可由特殊函数类表出。本文假定破裂速度是时间的分段函数。
In this paper, the far-field displacements of the rectangular fault radiated by a fault with uniform velocity expansion are studied. The spectrum Fcm (ω) is obtained, and the analytical expression of the displacement factor f_cm (t) is given and it is pointed out that f_cm (t) can be represented by a special function class. This paper assumes that the rupture speed is a piecewise function of time.
