Abstract:

Based on the in-situ survey of Erlangshan landslide and its controlling design data, a finite element program PCEP2D using contact elements, considering the interaction characteristics of anti-slide pile with prestress cable, is improved. Then, displacement, bending moment, stress distribution of contact elements along the pile are calculated. Moreover, comparing with traditional “m” method and monitoring data, it is shown that the engineering control effect of anti-slide piles is better.

Key words: anti-slide pile with prestress cable, problem of pile-soil contact, finite elements, post evaluation of engineering control effect
