Large Scale Model Test Study on Characters of Micropile in Landslide
This paper is to explain the large-scale physical model test of the interaction between the micropile and landslide to research on the force, deformation destroy pattern and bending moment distribution regularity of micropile affected by the landslide.The result of the experiment shows that the damage placed around the sliding surface and the destroy pattern is the combination of bending and cutting.The part of 15 times the pile diameter above and under the surface was quite affected by the landslide.The other part of the pile was almost of the same distortion with the soil around.When the micropile was destroyed, the displacement of the pile top was a quarter of the pile diameter, but the micropile still contained the skid resistance because of the force offered by the side reinforcement of the pile.Being different from the ordinary skid resistance pile, the bending moment distribution of micropile is located around the slide surface and the loaded segment of the pile bore the reserved bending moment.
