Abstract
For bridge engineering on steep slope, where the deformation of piled bridge foundation is strictly controlled, stabilizing piles are sometimes installed to minimize the soil shear deformation around the bridge foundation. A limited number of work has been carried out about the effects of stabilizing pile on the behavior of piled bridge foundation on the slope. In this study, model test and numerical simulations were carried out aiming at clarifying the lateral behavior of piled bridge foundation and stabilizing piles on steep slope. Evolution of bending moment in piles, soil pressure around piles, and lateral displacement of piles and soils were monitored throughout the model test. Model test suggested that back stabilizing piles subjected to much larger bending moment along the pile and force that acts on piles above the sliding surface than those of bridge piles. Numerical analyses were carried out to optimize the location of stabilizing piles. Front stabilizing piles should be located close to the bridge foundation. The optimum position for back stabilizing piles was 3 to 5 times of stabilizing piles width away from the bridge foundation.
