The Application Of Anti-slide Pile In The Traction Control Of Hill-creep

As an effective engineering measure to control landslide disasters,the construction practice is often ahead of the theoretical research.Although a large number of landslides have been treated at the anti-skid piles at home and abroad,it does not mean that the design calculations are consistent with the actual force and deformation.Or tend to be practical.It may often be the result of overly conservative design.On the basis of studying the theory and experience of slope slope management at home and abroad,the application and design method of anti-slide pile in slope disaster management are further discussed.The formation mechanism and stability analysis theory of slope instability,calculation method of landslide thrust,mechanism of action of anti-slide pile and calculation of internal force are described.Based on the example of anti-skid pile treatment project on the right side of the E-ramp of Luoxi interchange on Shenhai high-speed double-track(Quanzhou section),the stability of slope was analyzed by means of transfer coefficient method and the stability coefficient was calculated by Janbu method and Bishop method.By using cantilever pile method,elastic foundation frame model and plastic deformation theory calculation method,the mechanical model is established,calculation of internal force of Anti-Slip and the calculation results and actual monitoring values are compared.The reasons for the calculation deviation and the limitations of each calculation method are analyzed.At the same time,the construction difficulties and the key to the success or failure of the treatment of landslide in the anti-slide pile are summarized and reflected,and the development of anti-slide piles in the treatment of slope landslide is forecasted.In this paper,the whole process of anti-skid pile control landslide disaster from exploration,design to construction and operation and monitoring is carried out through the case study.This makes it easier to make a more accurate and scientific evaluation of the theoretical verification and the deformation,stability and control effect of the landslide,so as to be used as a reference for similar engineering practices.
