Abstract

In this paper, the synergetic effect of bi-directional geogrid on pavement structure layer is studied based on roadbed stability. The characteristics and regularities of stress and deformation of bi-directional geogrid in pavement structure layer are analyzed in detail. A new method of bidirectional geogrid reinforced soil is introduced. The force characteristics of bidirectional geogrid under the action of drawing are analyzed, and the formula of drawing resistance of bidirectional geogrid is derived. Subsidence of the pavement structure layer mainly comes from foundation settlement of the new splicing road, and the post-construction settlement of the spliced new road is equal to the total settlement of the position of the spliced new road in the reference period, and the settlement and splicing caused by the old road load at this position have the sum of settlements in the state.
