Pore water pressure characteristics of semi-rigid base for cement concrete pavement

doi: 10.19818/j.cnki.1671-1637.2012.01.002
More Information
  • The pore water pressure of semi-rigid base for cement concrete pavement was simulated by using finite element analysis software ABAQUS based on poroelasticity, and the distribution laws of pore water pressure along the base depth were calculated under different external loading conditions and pavement structures. Analysis result shows that in water-saturated state, pore water pressure decreases with the increase of surface thickness, surface elastic modulus, base thickness and base permeability, but increases with the increase of base elastic modulus. The elastic moduli of surface and base have no obvious impacts on pore water pressure. Meanwhile, pore water pressure linearly increases with the increase of traffic load. With the same load, denser load distribution impacts pore water pressure distribution more significantly. Loading modes only influence the dissipation of pore water pressure. With the increase of vehicle speed, pore water pressure increases, and its dissipation becomes fast.
