摘要
地震模拟振动台试验测点多,加载工况多,采集到的数据量大,且受噪声等因素干扰,测试数据与真实信号间有一定的差别。只有将测试数据经过科学的处理、修正和分析,去伪存真,才能得出正确的试验结果和结论。简要介绍桩-土-桥梁结构相互作用地震模拟振动台试验项目的概况,详细论述该试验数据的处理思路与方法,为以后相关试验研究提供参考。
In the test of seismic simulation vibrating table there are multiple measuring points, many loading conditions and plenty of collected data, and the test data are somehow different from real signals due to interference of factors such as noise, etc. Only if the test data are processed, modified and analyzed in scientific way for eliminating the false and retaining the true, can correct test results and conclusions be acquired. This paper simply introduces the overview of the test program of the seismic simulation vibrating table under the interaction of pile - soil - bridge structures and expatiates ideas and methods for processing the test data so as to provide a reference for the relevant tests in the future.
