Study On Seismic Response And Deformation Failure Mechanism Of Bedding Rock Slopes Within Weak Interlayer

Bedding rock slope within weak interlayer is one of the most common slope types. Its seismic response law and deformation failure mechanism are the basis for seismic design of Slopes. Until now, the study results of this field are too short to meet the demands of practical engineering. Through numerical simulation and large shaking table model test, the acceleration response law and deformation failure mechanism of bedding rock slopes within weak interlayer are studied under earthquake. The obtained results could provide valuable proof for seismic design of similar slopes.The main works of this thesis are as follows:1. The effects of manner of ground motion input and weak interlayer parameters of bedding rock slopes within weak interlayer on slope surface acceleration amplification effect are studied.2. The effects of slope height, slope angle, thickness of weak interlayer, dip angle of weak interlayer and location of weak interlayer on slope surface acceleration amplification effect of bedding rock slopes within weak interlayer are studied, and seismic response laws of bedding rock slopes within weak interlayer are summarized.3. The effects of slope height, slope angle, thickness of weak interlayer, dip angle of weak interlayer and location of weak interlayer on slope deformation failure mechanism of bedding rock slopes within weak interlayer are studied, and seismic deformation failure mechanism of bedding rock slopes within weak interlayer are provided.4. Taken Tangjiashan landslide during Wenchuan earthquake as the prototype, the large shaking table model test is designed and executed, its deformation failure mechanism and phenomena are analyzed.
