Analysis of pressure on the roof of a culvert underneath a ditch with compressible material covered by a geosynthetic layer
The load reduction mechanism of compressible material filled ditch covered with a geosynthetic layer is investigated. A mathematical model of the pressure on the roof of the culvert is established. Equations for calculating the earth pressure acting on the geosynthetic layer are derived. Considering the support effect of the compressible backfill underneath the geosynthetics layer, an equation is derived to calculate the deflection of the geosynthetic layer under the embankment fill loading. The pressure acting on the roof of the culvert is calculated by force analysis. The predicted results by the proposed method agree well with the test results.
