In order to explore the influence of different anchoring parameters of anchor on the stability of bedding rock slope, based on the numerical model of anchor rod considering the axial force and lateral force, the local force element of UDEC is embedde. For a bedding rock slope, the influence of anchor length, anchor angle, bolt spacing and layout on slope stability was analyzed. Based on the orthogonal test, the optimal anchoring scheme was proposed. The results show that: there is an effective length of anchor rod, and within the effective length, there is a linear relationship between the length of anchor and the safety factor of slope; there is an optimal anchor angle of anchor rod, and the larger the length of anchor rod, the smaller the optimal anchoring angle; the larger the distance between bolts, the smaller the safety factor of slope, and the decreasing rate of safety factor gradually decreases with the increase of spacing; the slope safety factor and bolt amount are used as evaluation indexes Index: through orthogonal test, the optimization design of anchor parameters of equal length support is carried out, and two better anchorage test schemes are obtained; the influence of anchoring parameters on slope stability from large to small are: bolt spacing, anchor length, anchor angle; the improvement of slope stability by anchor arrangement is from long to short, equal length, from short to long. When considering the layout of anchor bolts, the strata that the anchor bolts cross should be matched with the displacement of the slope.
