摘要:
为了给出土-结构动力相互作用大型振动台试验中模型地基设计的一般原则,结合各国已有的典型试验中模型地基的动力响应实测结果,以加速度峰值放大系数及其傅里叶幅值谱为分析依据,从边界效应、模型地基高度、土体含水量及地震波输入次数4个方面对模型地基的振动性态进行了比较分析。结果表明:土箱刚性、土的自振特性、地基高度、土体含水量及地震波的输入次数是影响模型地基动力特性的主要因素,并提出了相应的控制原则。该结论可为同类试验中模型地基的设计和试验的顺利开展提供有益的参考。
Abstract:
The general principle of large scale shaking table test of soil-structure dynamic interaction was investigated. Taking the amplification coefficients of peak acceleration and its corresponding Fourier amplitude spectrum as main factors, the measured results of existing typical shaking table tests were analyzed and the vibration behaviors of foundation model were compared in terms of boundary effect, height of foundation model, moisture content of soil and numbers of input seismic waves. The results show that the main factors affecting vibration behavior of foundation model are stiffness of soil box, self-vibration behavior of soil, foundation height, moisture content of soil and numbers of input seismic waves. At the same time, the corresponding control principles are proposed. These conclusions will be very helpful for the future test design of foundation model.
