“…The reinforcement of the soil is mainly based on the surface friction between the soil and the geogrid and the bite force between the cross ribs of the geogrid and the soil ( Figure 2 a); the support of the surrounding rock is mainly based on the tensile strength to withstand the load from the geotechnical body ( Figure 2 b). The high-strength steel wire added in the steel-plastic geogrid has superior tensile properties, which makes it different from the ordinary geogrid [ 31 ]. It has better tensile and bearing properties and great potential in the field of bolt mesh supporting.…”

Wire mesh is a common material for bolt mesh supporting structures, but its application in engineering has revealed many defects. At the same time, with the development of new materials for civil engineering, the new material mesh performance and cost show outstanding advantages over wire mesh. In this paper, the feasibility of replacing wire mesh with steel-plastic geogrid as an alternative material is carefully studied through indoor tests and field applications. The following conclusions were drawn from a comparative analysis with wire mesh, mainly in terms of mechanical properties, engineering characteristics, and construction techniques: (1) in terms of mesh wire strength, wire mesh is slightly better than steel-plastic geogrid, but in the case of similar tensile strength, the amount of steel used per unit length of steel geogrid bars is only 36.75% of that of steel-plastic geogrid, while the tensile strength of the high-strength steel wire attached to the steel-plastic geogrid belt is about 3.3 times that of steel bars; (2) in terms of junction peel strength, both values are similar, with the injection-moulded junction being 1154.56–1224.38 N and the welded junction of 4 mm mesh being 988.35 N; (3) in terms of the strength of the mesh, steel-plastic geogrid is better than wire mesh, and with the same mesh wire strength, the bearing capacity of steel-plastic geogrid is increased by about 63.17% and the contribution of the mesh wire bearing capacity is increased by 83.66%, with the damage mainly being in the form of wire breakage in the ribbon causing ribbon failure, leading to further damage to the mesh; (4) in terms of the engineering application of steel-plastic geogrid compared to wire mesh, the utilization rate of mesh increases by about 24.99%, the construction efficiency increases by about 14.10%, and the economic benefit increases by about 45.31%. In practical application, the steel-plastic geogrid has good adhesion with surrounding rock and strong corrosion resistance. According to the above research analysis, the steel-plastic geogrid is feasible to replace the wire mesh for bolt mesh supporting.

Anchor network support is an effective method for rocky slope support, but the defects of metal mesh in anchor network support structure to lead to the decrease of support effect and increase of support cost, which cannot be ignored. In view of the disadvantages of the metal mesh support, the steel-plastic grid is introduced into the anchor mesh support structure. In order to study the mechanical properties of steel-plastic grating and its application effect in rocky slope support, the influence mechanism of mesh size and node form on the mechanical properties of steel-plastic grating was studied by indoor experiments, and the feasibility of applying steel-plastic grating to high slope support structure was investigated by field tests. The conclusion of the study shows that the strength is maximum when the mesh size is 1:1 and the force distribution is uniform, but for the unidirectional force situation, the steel-plastic geogrid with a transverse to longitudinal ratio of 1:1.5 mesh is more economical. The influence law of nodal protrusion on the reinforcing effect of steel-plastic grating. The friction coefficient of the interface of steel-plastic grating is related to the interface of tendon and soil, and the friction coefficient of the interface is proportional to the mesh size, and the degree of influence of the nodes on the friction resistance is larger, and the larger the nodes, the better the reinforcement effect. The feasibility of steel-plastic grating applied to high slope support structure provides experience for similar construction projects.
