Numerical Investigation on Dynamic Response Characteristics and Deformation Mechanism of a Bedded Rock Mass Slope Subject to Earthquake Excitation

In order to systematically reveal the dynamic response characteristics of rock mass slopes subject seismic excitation, time-domain and frequency-domain analyses are used investigate a bedded slope from multiple perspectives, using two-dimensional numerical analyses. Based on simulation results, influence weak structural planes propagation waves in is analyzed. The analysis suggests that topographic geological conditions have an slope. effects ground motion direction identified. addition, according analysis, impacts surface, elevation, plane also clarified. intrinsic investigated by Fourier spectral modal deformation relationship between different natural frequencies slope, predominant frequency wave, discussed. Moreover, failure mechanism This work provides reference for this type
