Experimental Study and Numerical Simulation of the Effect of Rigid Pile Composite Foundations on Slab Culverts

For culverts installed in soft soil, the rigid composite pile foundation is used for soil treatment, and stresses around are complicated. Centrifuge experiments numerical simulations conducted to investigate vertical earth pressures settlement over a slab culvert under high backfill foundations treated with piles. The influences of lateral length spacing on at top analysed, they have significant effects pressure coefficients. It also indicates strong correlation between height high-backfill culvert, there uniform surface where interior exterior prisms same level. According experiments, decrease increasing spacing. Numerical were using finite element software Midas GTS evaluate performance experiments. Further, recommendations selecting an appropriate provided.
