EVALUATION OF EFFECTS OF SEEPAGE ON LANDSLIDE REINFORCED BY ANTI-SLIDING PILES
渗流对抗滑桩加固滑坡后的影响效果评价

The anti-sliding piles have been used in the treatment of geological hazards;the construction technology and theories of anti-sliding piles have been researched and developed.After the construction of the anti-sliding piles is completed,the effective seepage section of landslide will diminish,the underground water level of landslide will increase,the unit weight of landslide will increase but the effective cohesion and friction angle of sliding zone of landslide will decrease.The designed anti-sliding stability of landslides after pile construction is studied.The effects of landslide treatment by anti-sliding piles are also investigated by using volume average method,self-consistent method and Hashin-Strikman method;an available method is proposed to evaluate the effectiveness of anti-sliding pile reinforcement.Finally,the stability of landslide reinforcement by anti-sliding pile is performed.The effect of anti-sliding pile treatment is evaluated.
