Coordination Characteristics Analysis of Deformation between Polymer Anti-Seepage Wall and Earth Dam under Traffic Load

Polymer anti-seepage walls have been widely used in the reinforcement projects of earth dams. Dam crest is always supposed to meet requirements traffic load which has significant influence on dam body and wall. In order analyze coordination characteristics deformation between polymer wall under loads, a 3D finite element model an that considers coupling effect seepage field stress was established. Besides, amplitude, vehicle speed driving position analyzed, with displacement difference wall, Mises subsidence as indicators. The results show that, compared speed, amplitude exerted greater impact dam. variation range caused by axial change reached 87.1%, while resulted from 90.3%. That is, when passing light axle passes quickly over it less
