Summary:The invention provides a method for designing a roadway anchor rod support in a strong corrosion and impact environment. The method comprises the following steps: determining use parameters of the anchor rod support in a roadway hypersalinity water corrosion environment; preparing corrosive water to corrode the anchor rod support under stress; determining the quantitative relationship between the static load mechanical property and the shock resistance of the anchor rod support and the corrosion environment and the corrosion time; an anti-corrosion treatment process of the anchor rod support is determined, and anti-corrosion treatment is conducted on the anchor rod support; the impact danger magnitude of the roadway and the impact kinetic energy around the roadway are determined; determining the absorption energy of the anchor rod support; and determining the parameters, the anti-corrosion method and the grade of the anchor rod support. According to the method, the strong corrosivity and the strong impact of
