MODEL TEST STUDY ON LANDSLIDE REINFORCEMENT WITH SINGLE MICROPILE

This paper uses landslide and micropile model tests to examine the control mechanism, sliding force and the damage form of single micropile for landslide reinforcement. The test results show that the micropile can enhance the stability of landslide effectively. After the landslide is reinforced with micropile, the stability coefficient of the landslide can be increased from 0.96 to 1.35. The landslide pushing force and the landslide bedding resistance are found to have triangle distribution. The focus of the resultant force approaches to the sliding face. The micropile damages near the sliding face. The damage forms of micropile can be defined as cutting and bending failures.
