To resolve the deficiencies of the calculation model for anti-sliding pile with prestressed anchor cable

a calculation model that considers prestress and landslide thrusting stage according to the actual construction process and loading conditions of anti-slide pile with anchor cable was established. The impact of prestress loss of anchor cable and displacement of pile in construction stage on displacement compatibility of pile-anchor cable is considered. Meanwhile

the method to calculate the internal forces and deformation of anti-sliding pile with prestressed anchor cable was established based on weighted residual method. A calculation procedure of anti-slide pile with anchor cable was created based on Matlab platform

which was used to analyze engineering examples. The results were compared with those obtained from the conventional calculation model. It is shown that the improved model can incorporate the effect of the special process of anti-slide pile with anchor cable bearing active load in the prestressed stage on displacement compatibility of pile-anchor cable. Also

the improved model properly takes into account the prestress loss of upper anchor cable

which is caused by the lower anchor cable in prestressed stage. Furthermore

compared with the conventional calculation model

the improved model is more in line with the engineering practice.
