Steel-plastic geogrid greatly improves the stability of surrounding rock in the supporting project due to the qualities, such as high strength, high toughness and less creep deformation. Through the geogrid mechanical properties analysis, tensile strength, deformation and creep test and field experiment and so on, we researched and analyzed steel-plastic geogrids’ characteristics and supporting effect, and concluded the influencing factors of steel-plastic geogrids’ characteristics, load-time curve and the steel-plastic geogrids’ variation under different temperature. We explained steel-plastic geogrids’ supporting effect through specific examples of projects. The results of the studies are listed as follows: (1) Steel-plastic geogrid has good resistance to deformation and node failure of roadway surrounding rock deformation, which has good tensile property, creep property and deflection performance; (2) It is feasible to support the surrounding rock by forming a whole combined joint support with steel- plastic geogrid and high-strength prestressed anchor rod.
