YANG Bo-xiong, HU Xin-he, CHEN Zhi-gao, et al. Data processing and rock & soil frequency spectrum characteristic analysis of microtremor signal[J]. 2008, 29(3).DOI:
Frequency spectrum is one of the most important dynamical parameter for microtremor. Frequency spectrum characteristics of microtremor signal is closely related to the thickness of ground covering layer and the stiffness variation of overburden layer
which can reflect not only the type characteristic of rock and soil layer
but also the dynamic characteristic of project site. The current method that analyzing commonly the dynamic characteristic of site by microtremor signal has been discussed
researched and compared in detail. Meanwhile
the diversification rule has been analyzed through example; and the estimation of power spectrum and the frequency response characteristic of micro-tremor signal to the site rock and soil mechanism are introduced deeply.
