摘要
Taking the anti-slide piles in one potential landslide treatment engineering as study object, this paper made a simulation and comparison of ordinary anti-slide piles and anti-slide piles with prestressed anchor cable by ANSYS. Through the strength reduction FEM and the traditional limit equilibrium method, the stability of landslide treated with these two kinds of supporting structure were analyzed, and the rules of the slope deformation and the plastic strain, internal force distribution of the pile body were studied. The results show that excavating the slope toe for unload can easily cause the landslide and the reasonable application of anti-slide piles with prestressed anchor cable and the ordinary piles can effectively improve the stability of landslide; under a variety of natural and saturated conditions, using anti-slide piles with prestressed anchor cable, the landslide deformation, the pile top displacement and the whole strain of pile body will be smaller than that when using the ordinary anti-slide piles; compared with the ordinary anti-slide piles, the stress and bending moment distribution of the anti-slide piles with prestressed anchor cable is more reasonable and the anti-slide pile with prestressed anchor cable can effectively control the deformation and displacement of the landslide, which is more favorable to ensure the stability of the landslide.
