Study On The Optimization Of Dalu Ditch Landslide Treatment In Wuqi

Landslide is one kind of universal geological effects. Traffic is usually broken, river channel is usually blocked, factories, mines, villages and farmland are usually broken, all of which are caused by the landslides which are taken more and more attention in the world. So landslide-block project and interaction of the slippery body become one of the hot issues that relevant scientific and technical personnel study in the field of engineering day by day . How to design a optimum landslide teratment plan economically and safely has practical value to national economy construction and development.This thesis regards managing the scheme in optimum seeking as the goal, anti-sliding piles is designed and calculated, and arched anti-sliding piles wall is simulated by finite element method on the basis of the project of dulu ditch slide treatment, on which the failure mechanism, stability analysis, treatment project and plan optimization , etc. are also based and carried on more comprehensive research. The concrete contents are as followed:Landslide thrust force calcuation, internal force and deformation and reinforcement calcuation of anti-sliding pile were analysis theoretically in the anti-sliding piles designation and calculation. Anchorage force is studied in the anchor cable anti-sliding pile.The traditional anti-sliding piles system is unevenly and unreasonable stressing, so in this thesis anti-sliding pile is set into arch shape. Then arched anti-sliding piles wall and traditional anti-sliding piles are simulated by finite element method, through the comparison of them, we can draw the conclusion that the first one is more reasonable.This text comes down for the example of the dulu ditch landslide, Dalu ditch landslide characteristic of deformation and destruction is researched after analyzing the cause of landslide. And the stability of the landslide is analyzed by many kinds of methods, which can provides basis to the landslide treatment scheme.In this thesis, some dispose project and feasible control engineer measures which specializing in arched anti-sliding piles wall for dalu ditch landslide prevention and elimination are proposed. And then some feasible paoject measures are calcuated and analyzed in detail, such as cut and backfilling, anchor anti-slide piles, cantilever piles, drainage engineering and slope protection, etc. The optimum scheme is confirmed by comparing with these schemes.
