Theory Analysis of Cement Concrete Pavement Structure Based on Existence of Disengaging Under Slab

Abstract:

Differential settlement of foundation will result in adverse state of cement concrete pavement, additional force is induced by self weight while existing disengaging under slab and fatigue life of pavement is affected. Mechanical model of existence of disengaging under slab is established under self weight and formula of stress and deflection of slab are derived by related theory of plate and shells based on existence of disengaging under slab induced by the shield driving method.
