| Abstract: | The vibration characteristics and dynamic responses of rock and soil under seismic load can be estimated with dynamic finite element method(DFEM).Combining with the DFEM,the vector sum analysis method(VSAM) is employed in seismic stability analysis of a slope in this paper.Different from other conventional methods,the VSAM is proposed based on the vector characteristic of force and current stress state of the slope.The dynamic stress state of the slope at any moment under seismic load can be obtained by the... |
