SHEAR STRENGTH OF THE SLIDING PLANE AT ZAOLIN LANDSLIDE AND ITS REINFORCEMENT

In this paper the authors first describe geologic conditions of Zaolin landslide. The shear strength of the sliding plane at Zaolin Landslide is then obtained based on laboratory tests, expert experiences and back analysis of the stability of the landslide. A reinforcement plan using anti-slide piles with pre-stressed anchor wires is suggested. Its design method and construction techniques are discussed in detail. Subsequent monitoring data confirmed the success of the suggested reinforcement plan.
