Lattice anchoring technology large-scale physical model test method

The invention discloses a lattice anchoring technology large-scale physical model test method. According to the method, homogeneous loess is used as a landslide medium, a landslide model is filled through a layer-by-layer compaction method, a sliding belt is preset, an anchor rod is completed through a drilling cast-in-place method, and a lattice beam is prefabricated with the use of fine aggregate concrete. A sensor is arranged to test the characters of a lattice anchoring system in the whole process from force bearing to damage during landslide drop, the landslide is slid through a vertical slope top loading method, and the deformation failure characters of the lattice anchoring system from force bearing to damage under the action of landslide are recorded. Recycling of an anchoring section of the anchor rod is effectively realized, and model test on the whole deformation failure process of the lattice anchoring system from installation to loading damage can be quickly and efficiently carried out for multiple times in a short period of time.
