Records of strong motion are often used as the ground motion inputs in earthquake analysis and in the design of structures. The design of underground structures, however, requires more than just the time history at any particular point on the earth's surface. It also requires the space-time variation of the ground motion. We have therefore developed several methods for generating a simulated space-time variation that includes strong ground motions recorded at observation points. This simulated variation is characterized by an apparent velocity and by a coherence function. Here we presented a case study using motion recorded during the 1995 Kobe earthquake.

在地震分析和结构设计中，强震记录常被用作地震动输入。然而，地下结构的设计需要的不仅仅是地球表面任何特定点的时间历史。它还需要地面运动的时空变化。因此，我们开发了几种方法来生成模拟时空变化，其中包括在观测点记录的强地面运动。这种模拟变化的特征是表观速度和相干函数。在这里，我们提出了一个案例研究，使用1995年神户地震期间记录的运动。
