Vertical earth pressure on the geosynthetic-soil interface is the key to estimate behaviors of geosynthetic sheets and surface settlement of low geosynthetic-reinforced embankments. New calculation methods of embankment backfills and vertical earth pressures on geosynthetic sheets considering static equilibrium are proposed. According to reasonable boundary conditions, a new approach for three behaviors of geosynthetics subjected to linear localized sinkholes is derived. It considers load transfer of embankments over voids, deflection of geosynthetic sheets over voids, and horizontal displacement of geosynthetic sheets in anchorage zones. Moreover, the values predicted by this study and other studies are compared with the results of the existing tests and finite element analyses. The comparisons validate the reliability and feasibility of the new improved approach.
