Background
The anti-slide pile is widely applied at home and abroad as an effective measure for stabilizing side slopes and landslides and reinforcing unstable mountain bodies, but in actual engineering, the anti-slide pile is influenced by the understanding degree of geological conditions, construction quality and various unknown conditions (such as earthquakes, heavy rainfall and the like), and engineering accidents of anti-slide pile failure do not occur. Once the anti-slide pile is damaged due to failure, the strengthening and treatment of the anti-slide pile are actual engineering problems which must be faced.
At present, the engineering measures adopted after the anti-slide pile fails have certain defects. (1) The prestressed anchor cable is adopted to reset and reinforce the failed slide-resistant pile, but when the inclination amplitude of the pile body is large, even if measures such as the anchor cable are adopted for correction, the slide-resistant pile still cannot provide effective resistance due to insufficient depth of the anchoring section, and the reinforcing effect cannot be realized. (2) When the roadbed filling is basically finished, if the inclined slide-resistant piles are dismantled and constructed again, the method is not feasible in terms of construction period, construction difficulty and engineering investment. (3) Rectangular anti-slide piles are additionally arranged between original anti-slide piles for reinforcement, the treatment and reinforcement effects can be achieved, but inclined anti-slide piles are not righted and repaired, and influence on engineering quality and engineering acceptance is inevitably caused in appearance. (4) The rectangular slide-resistant pile adopting manual hole digging is adopted for reinforcement, so that the problems that the construction period is long, the safety risk exists in manual hole digging construction and the like exist.
