Large scale model test study on single micropile in landslide reinforcement
摘要
Abstract
A large scale model test about single micropile and landslide was carried out. The force, damage form and bending moment of single micropile for landslide reinforcement are studied by several testing tools. The test results show that the damage form of single micropile is cutting and bending failure near the slip surface. The interaction effect between micropile and soil mass is obvious in the scope of fifteen times pile diameters above and down the slip surface, while unconspicuous outside the scope. The displacement of the micropile top is one-quarter of pile diameters when the single micropile damages. The damaged micropile still has skid-resisting capacity which provided by the pulling resistance of the steel. The bending moment of single micropile is different from that of the anti-slide pile. The bending moment of single micropile lies near the slip surface and the pile body above the slip surface effects negative bending moment.关键词
