Abstract：
In light of transverse slope requirements of airfield runways and the curved pattern of foundation settlement sections, a formula, which can be used to control the counter slope phenomenon induced by shield driving under pavement structures in the flight zone, is derived based on a assumption of compatible deformation between the pavement structure and foundation settlement. An allowable value [δmax /i] is also derived, with which no counter slope phenomenon can occur under differential settlement. The parameters involved in these formulas can be used to guide shield construction and reduce the possibility of the counter slope phenomenon in airfield runways.
