摘要
振动台台面运动能高精度地再现所要模拟的地震波，是模拟地震振动台试验的基本要求。本文从原理和实践两个方面对这一问题进行了研究。在讨论通过迭代方法逐步缩小再现地震波误差的基础上，给出了振动台试验中提高地震波模拟精度的补偿试验的方法和步骤。
It is a basic requirement that seismic waves are reappeared with high precision by the shaking tab1e movement in shaking table test. In this paper the problem is discussed in both princi- ple and practice. Based on studying how to reduce reappearance error by the iteration, the methods and procedures used in compensation test are put forward.
