A New General Solution of Axisymmetric Elastic Space Problem in Pavement Engineering

The general solution of the axial symmetry elastic space problem in cement concrete pavement is an elementary question. Combining Love method and Southwell method, operator was used variable selection process, displacement function introduced to express component by expression stress indicated obtained combining components, geometric equations, physical then substituted into equilibrium equation, biharmonic equation mathematical operation, finally, a new axisymmetric obtained. According proposed solution, mechanical calculation for slab on Winkler foundation carried out, curve at top surface top, middle, bottom were derived, results showed that feasible pavement. provided solving
