Dynamic Analysis of the Seismo-Dynamic Response of Anti-Dip Bedding Rock Slopes Using a Three-Dimensional Discrete-Element Method
نویسندگان
چکیده
Earthquakes are a major external factor that induce landslides. In order to systematically study the dynamic effects and failure mechanism of anti-dip bedding rock slopes (the slope trend is same as joint trend, while dip direction opposite direction) under seismic action (as well spatial structural planes in slopes), three-dimensional (3D) discrete-element numerical calculations were performed analyze with different angles, trends subjected natural sinusoidal waves. The results analyzed investigate amplification effect, change Fourier spectrum, mechanism, permanent displacement applied action. was calculated using Newmark’s method obtained discussed compared those from analysis 3D method. showed regularity distribution effect less clear than encountered planar problem (unidirectional or bidirectional dynamical loading), this leads having an overall rhythmical nature. wave decays high-frequency part bottom up slope, dominant frequency decreases. value much smaller approach. angle between has significant on mode, displacement, stability

Rock Slope Stability Analysis Using Discrete Element Method
Rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). Since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. Also, Rock slope instability is a major hazard for human activities and o...

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
