1.Geogrid application in highway and railway, can reduce the abutment and roadbed settlement difference, reduce vehicle and roadbed vibration, slow embankment structure deformation, ensure the safety and comfortable vehicle.
2.In backfilling adding geogrid, can increase the backfilling material shear strength and metaphase integrity, reduce mid-term fill quantity, the soft foundation treatment convenient and reduce the cost.
3.In the earth-rock profile design, by geogrid reinforced structure, can improve do dam stressed deformation performance, of the dam to avoid breaking and reduce quantity and project cost.
