An orthotropic contact model was adopted in this paper to simulate the contact condition in the interface of ultra-thin whitetopping(UTW).The ANSYS was utilized in the structural calculation.The critical loading position was determined: the middle of longitudinal joint edge was the critical location of tensile stress under panel bottom while panel corner was that of shearing stress at the interface.In calculation,increasing shearing strength and keeping interface continuous could reduce tensile stress under panel bottom.Overloading was an important cause of panel breakage,tensile stress under panel bottom leaped with overloading,and the weaker the structure combination was,the bigger stress ratio of overloading could be.This paper had a parametric analysis to determine the effects of asphalt thickness and modulus,concrete slab dimension and thickness,base modulus and contact conditions to tensile stress under panel bottom or interface shearing stress;the influence law could serve as a base in UTW design.
