| 摘 要： | 瑞利波频散特性测试是波速结构的面波探测方法中的关键环节。本文不进行速度结构的比较，而是直接与表面波谱分析方法比较所提取的频散曲线，从而将反演方法可能引入的不确定性因素剥离了出去，能够更客观地说明地脉动台阵方法的有效性和精度。在唐山26个场地进行的两种方法中美联合观测和分析结果表明。地脉动方法在83％的场地达到了与表面波谱分析方法相同的精度，是一种经济有效的场地瑞利波频散特性和波速结构测试方法。

| Abstract: | The evaluation of Rayleigh wave dispersion characteristic is the key step for detecting S-wave velocity structure.By comparing the dispersion curves directly with the spectra analysis of surface waves(SASW) method,rather than comparing the S-wave velocity structure,the validity and precision of microtremor-array method(MAM) can be evaluated more objectively.The results from the China-US joint surface wave investigation in 26 sites in Tangshan,China,show that the MAM has the same precision with SASW method in 83% of the 26 sites.The MAM is valid for Rayleigh wave dispersion characteristic testing and has great application potentiality for site S-wave velocity structure detection. |
