Abstract

Discussed the stability of MaJiagou landslide in ZiGui country in three gorges reservoir and the anti-slide pile design in three different conditions of reservoir impoundment and fluctuation. The stability coefficients of landslide all decrease in the three different conditions. Both the main landslide mass and the front secondary landslide may slide ensemble. Landslide control adopted anti-sliding pile and drain engineering. Emphatically introduced the layout, geometry size, landslide thrust calculation, internal force calculation and reinforcement design of piles. Using seventeen 2.0 m × 3.5 m section anti-slide piles of 6 m pile spacing and combining transverse drains with longitudinal drains to control landslide. The treatment scheme is economic and reasonable, the stability improves after controlled. It provides reference for similar landslide stability analysis and comprehensive control.
