摘要
通过对不同冻土层厚度上多层砖房微幅振动的检测，利用时域和频域识别方法，研究了冻土层厚度对多层砖房固有频率（平移和扭转）、振型和阻尼的影响．
Using microtremor measurement and identification method in frequency domainand time domain, the effects of frozen soils with different depths on frequency features, vibration mode and damping of multistory brick buildings are studied.
