Abstract:
The mechanism of the reinforeed bridge approach embankment with geogrid is firslly introdueed.Aecorling to the requirements of vertieal aeeeleration that human body travels with, the settlement require.ments of bridge approach are diseussed and the transition seetion length of reinforeed embankment for eomfortable driving is detemmined. The are assumplion is made to deseribe the settement curves and the Coulomb frie.tion is used to model the interlace characteristie between geogrid and soil. The stress of geogrid reinforeing theembankment is studied at last, the analytical expression to caleulate the axial tension forees of the geogrid isobtained, and it is veriied by the numerical simulation and practieal projeet.
