Loading Stresses Calculation for Road and Terminal Concrete Pavement of Port Areas

Abstract:

As per the problem of loading stresses calculation for road and terminal concrete pavement of port areas under moving vehicle loads and container loads, the configurations of moving vehicle loads and container loads are simplified as single wheel (single container leg) load, single axle single wheel (two container legs) load as well as multiple axle single wheel (four container legs) load. An unequal planar dimension double layered pavement model is adopted, and a set of general loading stress formulas for road and terminal concrete pavement of port areas are put forward. The influences of the side wheel load, adjacent axle load, two and four container legs load, planar size of concrete pavement slab and base extension as well as joint load transfer capacity etc. on the loading stresses in concrete pavement slab and base are thoroughly analyzed. At last, a comparison of results based on the finite element method and obtained with formulas is made to verify the agreement and precision of loading stresses, therefore, the research resultants can be used for the loading stress calculation for road and terminal concrete pavement of port areas under moving vehicle loads and container leg loads.
