Analiza efektywności modelowania cyfrowego drgań budynku wywołanych wstrząsami górniczymi

Dynamic occurrences caused by mining exploitation (e.g. the loss of rock mass stability) result in vibrations of both the rock mass and the building situated on its surface. There are many projects concentrating on measuring or predicting quakes mentioned above and vibrations caused by them. One of the ways of predicting vibrations is digital modeling (e.g. using the Finite Element Method). This type of modeling is restricted in many ways. The most important restrictions include difficulties in identifying digital model of rock mass and buildings, which makes the quality of test results in digital modeling still inefficient. In this paper, the quality of digital modeling is based on the comparison of building vibrations (modeled with FEM) with vibrations recorded with suitable geophysical devices. The basis of the comparison of modeled and measured vibrations is their spectral analysis.
