| description | The research on the mechanical characteristics of anti-slide pile is the key to the design of anti-slide pile.In the Three Gorges Reservoir area, there are multi-layer slide belts in some accumulation landslides.However, the current design method of anti-slide pile is only for single-layer landslides.Therefore, the research on the mechanical characteristics of multi-layer slide belt accumulation landslide anti-slide pile is of great significance.Based on the engineering geological characteristics of the accumulation landslide in the Three Gorges Reservoir area, this paper develops a physical test model of the accumulation landslide in the multi-layer sliding belt.The thrust is applied to the rear edge of the landslide to simulate the evolution process of the landslide, and the multi field information of the landslide anti-slide pile system is monitored at the same time.The test results show that in the evolution process of multi-layer slide belt accumulation layer landslide, the stress of pile body shows a good regularity.According to the change trend of slope surface displacement, the landslide evolution is divided into four stages, and on this basis, the pile stress is analyzed.There are two maximum values in the landslide thrust distribution diagram and the only maximum value in the soil resistance distribution diagram.The test results provide some theoretical support for the design of anti-slide pile. |
