注浆钢管微型桩加固滑坡的试验研究
Model Test on Application of Grouting Steel-Tube Micropiles to Landslide Reinforcement
摘要
Abstract
In order to investigate the reinforcing mechanism of grouting steel-tube micropiles on landslide, their control effects were analyzed from the displacements of slope top, slope surface and slope body through centrifugal model tests. The force characteristics of steel-tube micropiles reinforcing landslide were analyzed. The experimental results show that grouting steel-tube micropiles can effectively control the displacement of slope soil and prevent the generation of landslide, and only local shallow cracks are formed on the surface of slope. The maximum soil pressure on an anterior pile is 13.3% of the maximum soil pressure on a posterior pile to show that posterior piles bear large landslide thrust. The bending moment curve for an anterior pile changes from a reverse S-shape to an S-shape in the refinement process, while the bending moment curve for a posterior pile is S-shaped.关键词
