Analysis and application of effective embedded sections of pile sheet walls in mountainous slope areas
The pile slab wall is commonly utilized in slope filling projects with limited space,where the anchoring section of supporting piles is considered as a semi-infinite body.However,forming the anchoring condition of a semi-infinite body for the triangular body in front of piles on slopes proves to be challenging.In order to determine the effective anchoring section of a pile slab wall in mountainous slope areas,this study primarily employs Madis GTS NX finite element software for simulation and analysis.By altering the soil slope in front of piles,we obtain the variation trend of horizontal displace-ment at the top of piles and internal forces within pile bodies:Under identical conditions for other aspects of the pile slab wall,both horizontal displacement at the top of piles and internal bending moment within pile bodies increase simultane-ously with an increase in soil slope ahead of each respective pile.We summarize different starting positions for effective embedded sections based on various slopes.Through monitoring results from a practical project,calculated values align with monitored values,thereby validating the rationality behind our calculation method.This can provide valuable refer-ence for future design projects involving pile slab walls in mountain slope areas.
