| 英文摘要 | Due to topographical restrictions, transmission towers will inevitably be erected in areas prone to frequent geological disasters such as steep slope failure. Taking the Yanzi tower foundation landslide as the research object, the failure process of the tower foundation in a landslide and the corresponding failure mode under rainfall were studied through physical model testing and numerical theoretical analysis. Firstly, the planned design and testing process of the physical model test of the tower foundation landslide under rainfall were introduced. Secondly, the failure process of the tower foundation at different positions of landslide under rainfall was revealed. Then, the failure mode of the tower foundation landslide under rainfall was proposed. Finally, the failure mode of the tower foundation under rainfall was determined. According to the observed displacement of the tower foundation during a landslide in the model test, the instability of the toe of the landslide caused by scouring caused traction damage to the landslide. The tower foundations on the landslide and outside the trailing edge of the landslide became unstable and collapsed along with the landslide, while the tower foundation below the landslide remained stable. During the deformation stage of the landslide, there was no shear failure and no tipping damage to the tower foundation. If the potential landslide on which the tower foundation is located is unstable under heavy rainfall, the tower foundation may slide along with the potential landslide passing through the bottom of the tower foundation, which is consistent with the result of physical testing. |
