- By comparing the simulation results with the test results, the applicability of this model to the translation failure of retaining walls was verified. Displacement under different base friction coefficients was analyzed, which further verified that the model conformed to the anti-translation checking conditions in the code.
- SPH analysis was carried out on the motion response of retaining walls with different base lengths. The overturning situation and overturning angle of different retaining walls were compared. It was verified that the model conformed to the anti-overturning checking conditions in the code.
- Overall, the model accurately describes the motion response of the retaining wall under different conditions after soil impact. The model proved to be suitable for practical engineering cases and can provide a brand new numerical simulation platform for the design and checking calculation of retaining walls and the impact of soil on structures after landslides.
