Deformation of Geosynthetic-Reinforced Soil Beam Subjected to Localized Sinkholes by the Winkler Model
A new analytical solution to evaluate the vertical displacement of the geosynthetic reinforcement in the void and anchorage zones is derived, based on the Bernoulli-Euler beam model on a Winkler foundation as well as the continuities and boundary conditions of the moment and shear force, and considering the soil arching effect in embankments above geosynthetic sheets. Moreover, a formula for the inertia moment of the reinforced soil beam is proposed according to cross-section static equilibrium. To validate this new analytical method, the deflection values of the geosynthetic reinforcement over voids calculated by the proposed and existing methods are compared with those by existing experiment and numerical simulation. The influences of the void width, the coefficient of subgrade reaction, the Young’s modulus, height of the geosynthetic-reinforced soil beam, and the tensile modulus of geosynthetic material on the deformation of geosynthetic reinforcement are discussed. The results show that the void width and height of the reinforced soil beam have significant influences on the deflection of geosynthetic reinforcement over voids.
