| 英文摘要 | As a combined supporting structure, the anchor cable and lattice beam have a complex interaction with the slope body. In order to investigate the seismic behaviors of the slope reinforced by anchor cable and lattice beam, a large-scale shaking table test was carried out on a slope model (geometric scale of 1:20) by applying recorded and artificial seismic waves with different amplitudes. The acceleration and displacement of the slope, the displacement of lattice beam and the axial force of anchor cable were obtained to study the interaction between the slope and the supporting structure. The test results show that: (1) the acceleration responses of the slope at different relative elevations display obvious nonlinear characteristics with increasing of the peak ground acceleration (PGA) of the inputted seismic waves, and the weak intercalated layer has a stronger effect on acceleration amplification at the upper part of the slope than that at the lower part of the slope; (2) the frequency component near the second dominant frequency is significantly magnified by the interaction between the slope and the supporting structure; (3) the anchor cables at the upper part of the slope have larger peak and residual axial forces than that at the lower part of the slope, and the prestress loss of the anchor cable first occurs at the top of the slope and then passes down; (4) the peak and residual displacements inside the slope and on the lattice beam increase with the increase of relative elevation. When the inputted PGA is not greater than 0.5 g, the combined effect of anchor cable and lattice beam is remarkable for stabilizing the middle and lower parts of the potential sliding body. The research results can provide a reference for the seismic design of such slope and the optimization of supporting structure. |
