The geogrid include: Plastic Geogrid Plastic Geogrid glass fiber geogrid warp knitting polyester geogrid composite geotextile fiberglass grating Bouguer gate is a thermoplastic polypropylene, PVC and other polymer-polymer or molded by a two-dimensional grid or a certain height of three-dimensional grid, gridded, when used as civil engineering, called the geogrid. Geogrid applications ⒈ geogrid used to increase the bearing capacity of the road (to) base, extend the service life of the road (to). ⒉ geogrid used to prevent road (to) surface subsidence or cracks, keeping the floor neat. ⒊ geogrid is used to facilitate the construction, saving time, effort, shorten the construction period, reduce maintenance costs. ⒋ geogrid for Culverts to prevent cracks. The geogrid ⒌ used to enhance the soil, prevent soil erosion. The geogrid ⒍ used to reduce the thickness of the cushion, and cost savings. The geogrid ⒎ for the stability of the supporting slope grass mat green environment. Geogrid can effectively deadening seismic force transmission, and enhance the embankment earthquake stiffness, strength, and stability has an important role. The successful application of geogrid, is expected to reduce the common variety of high-intensity earthquake zone embankment diseases, improve the earthquake disaster reduction capacity of the road. The current road, railway seismic design specifications were not made the corresponding provisions of the seismic performance of geogrid reinforced embankment. At home and abroad on geogrid reinforced embankment seismic effect, reinforcing effect, the study of the mechanism of action, few analytical methods are less developed and mature, not much actual work sites test data accumulated.
