Landslide, rock falling, river erosion are the serious geological disasters that make effect on Zhongxian-Wuhan gas pipeline safety, and the landslide is the most outstanding disasters among them, and anti-slide pile was often used to reinforce landslide mass. However, computation and design of anti-slide pile approximation in actual`dge issues that worth further studying. Irrational design of anti-slide pile can result in landslide risk still exist, landslide is still possible to failed, and conservative design although eliminate landslide risk, and at same time it causes waste of money. So it has important theoretical and engineering significance to verify the accuracy of the design and assess control effectiveness of landslide based on internal force monitoring of anti-slide pile. Based on axial force monitoring main reinforcement inner anti-slide pile, this paper gets the factual moment variation of anti-slide pile of Shunxi No.1 at different times, and compared factual moment with theory moment calculated by the commonest M method. The result showed that the theory measurement calculated by M method is much more then factual moment, so it is safe to compute internal force of piles by M method. Currently, it indicates that the landslide after treatment is under a stable state because of less stress acting on the pile, and the main threat to the gas pipeline will vanished, and the expected control aim is achieved. It has great reference for internal force design of anti-slide pile retaining structure and control effectiveness evaluation.
