Test device and test method for simulating stress characteristics of bridge abutment foundation
The invention relates to the technical field of geotechnical engineering landslide model test design monitoring, in particular to a test device and test method for simulating stress characteristics ofa bridge abutment foundation. The test device comprises a landslide scale model, a force loading system and a plurality of testing elements; the bridge abutment foundation and an anti-skid structureare arranged in the landslide scale model, wherein the anti-skid structure is arranged between the bridge abutment foundation and the front edge of a landslide; the force loading system is connected with the anti-skid structure and is used for loading pulling force towards one side of the front edge of the landslide step by step on the anti-skid structure; and the plurality of testing elements areused for monitoring testing data of all detection points in the process from stress to instability of the front edge of the landslide. According to the test device and test method for simulating stress characteristics of the bridge abutment foundation, continuous changes of a traction type landslide in the process from stress to instability of the front edge are truly simulated, and the stress and deformation characteristics of the bridge abutment foundation when the front edge of the landslide on the traction type landslide is unstable can be researched; and the testing device is simple in structure and easy to obtain, the testing method is controllable in process condition and high in operability, and a relation between landslide front edge soil deformation and bridge abutment foundation deformation can be easily obtained.
