Field Test and Numerical Analysis on Deformation Response of H-Type Antislide Pile: Case Study of Longjiayan Landslide, China
Publication: Natural Hazards Review
Volume 22, Issue 4
Abstract
Landslides are regarded as significant geological hazards worldwide and threaten many people. To effectively prevent the occurrence of landslide disasters, antislide piles are widely used for the treatment of landslides. However, for some massive landslides (landslide thrust ), the retaining effect of the common antislide pile is very poor. The h-type antislide pile is a novel retaining structure and has proven effective in engineering practice for the treatment of massive landslides. In this study, the Longjiayan landslide (a massive landslide) was taken as the research object. The strain and displacement of the h-type antislide pile were monitored using distributed optical fiber sensing technology. In addition, the variation laws of the moment and displacement of the h-type antislide pile were obtained. Moreover, a numerical calculation model for the Longjiayan landslide was established based on the monitoring results. The influences of different pile parameters on the supporting effect were studied, and the optimal values of the pile parameters were determined. The results show that the retaining effect is optimum when the crossbeam length is equal to , the pile spacing is equal to , the anchor ratio of the rear pile is equal to 0.33, and the anchor ratio of the front pile is equal to 0.35.
