Zusammenfassung: | The invention discloses a method for acquiring dynamic response data of a passive pile-slab stone blocking wall in collapse rockfall geological disasters, which comprises the following steps: dividing an impact force-deformation relation curve of a reinforced concrete pile-slab wall under the impact of rockfall into three stages: stage I: an elastic loading stage at the initial stage of collision; determining the contact force between the rockfall and the reinforced concrete sheet-pile wall to be elastic contact; stage II: a plastic damage loading stage of the concrete pile-slab wall, wherein when the contact impact force exceeds the yield strength of the wall body, the concrete pile-slab wall generates plastic deformation and is damaged; and stage III, unloading stage: when the reinforced concrete sheet-pile wall reaches the maximum compression deformation, reducing the falling stone impact speed to 0, and the elastic deformation accumulated by the wall body can be rebounded and released.
