Calculation Method of Bridge Double-pile Structure in High-steep Transverse Slope
According to the structure and load characteristics of bridge double-pile foundation in high-steep transverse slope, the new model of piles-slope interaction and piles-soil interaction was established: The back pile beard thrust was simplified as slope sliding thrust and active earth pressure at critical sliding surface, lateral soil resistance of the double piles obeys the linear growth rule (), and the acting force of inter-piles soil to front pile was assumed as the functions of pile space, pile width (diameter) and sliding body width, which can fully reflect the effect of inter-piles soil and sliding body on the soil pressure transmission. Then, the differential equations of pile sections with different characteristics were deduced, and the displacement calculation method of the new structure was obtained by finite difference solution. The comparison between theoretical solutions and laboratory model test data shows that this method can be applied for practical engineering and provide a calculation reference for this new structure design.
