The Effect of Slide Mass and Pile Stiffness on Residual Thrust on Stabilizing Piles

Abstract:

As for stabilizing piles used to reinforce landslides, landslide thrust acts on their upslope sides but slope resistance acts on their downslope sides at the same time. In fact, the results that the former subtracts the latter are effective loads on piles, which can be called residual thrust on piles. The interaction between pile and rock or soil mass is simulated by elastoplastic finite element method in the paper. And the effect of slide mass and pile stiffness on residual thrust on stabilizing piles is analyzed. The results show that residual thrust on a stabilizing pile become more and more with elastic modulus of slide mass or the pile being increased. Meanwhile, action point of the resultant of residual thrust on the pile is lower and lower with elastic modulus of slide mass being increased but it is higher and higher to some extent with elastic modulus of the pile being increased. These results can be of theoretical reference for comparison and selection of various design plans of stabilizing piles.
