摘要:
为了在振动台试验中确定土-桩体系的基础频率,采用环境噪声、人工白噪声、正弦波以及人工地震动等4种激励形式,根据各种激励方式的特点,分别选用适当的计算方法对试验结果进行了分析。计算结果表明:通过选用合理的分析方法,各种激励方式作用下均能得到体系基础频率的可靠估计,环境噪声激励方式实施最为简单,但需要对其试验结果进行大量的统计分析工作;正弦激励方式的数据处理最为简单,但其激励实施较为耗时,且对体系的扰动较大;人工白噪声激励和人工地震动激励是较为推荐的激励方式,在实施中应注意人工白噪声的生成质量和人工地震动设计反应谱的选取合理性,以提高试验结果的可靠性。
Abstract:
In order to determine the fundamental frequency of soil-pile system in shaking table test, four excitation forms such as environmental noise, artificial white noise, sinusoidal wave and artificial ground motion are adopted. According to the characteristics of various excitation methods, appropriate calculation methods are selected to analyze the test results. The calculation results show that reliable estimation of the fundamental frequency of the system can be obtained by selecting reasonable analysis methods for each excitation mode. The implementation of environmental noise excitation is the simplest, but it needs a lot of statistical analysis of the test results. Data processing for sinusoidal excitation is the simplest, but the implementation of this excitation is time-consuming and has a large disturbance to the system. Artificial white noise and artificial ground motion excitation are more recommended methods. In the implementation, attention should be paid to the generation quality of artificial white noise and the rationality of design response spectrum of the artificial ground motion, so as to improve the reliability of test results.
