To explore the stability of highway slope anchor bolts combined with plant root slope protection, based on the ecological slope protection project of a highway in Dalian. Based on the strength reduction method, the finite difference software is used to compare and analyze the horizontal deformation, soil settlement, slip surface position, and safety factor of the slope under the conditions of no support, ecological slope protection (early), and ecological slope protection. According to the calculation results of slope deformation and safety factors under different conditions, the stability of the highway slope is evaluated. The results show that the maximum deformation of the slope occurs in the middle of the slope surface, which should be supported by centralized support. After the support, the maximum deformation of the slope moves to the toe of the slope; The safety factor of the slope increases with the increase of the cohesion and internal friction angle of the rock-soil mass of the slope. The cohesion has a greater influence on the slope stability when the slope angle is larger, and the internal friction angle is opposite; The safety factor increases linearly with the increase of bolt length, and the slope stability will not continue to improve when the length of the bolt exceeds the effective anchorage length. At this time, the slip surface will move to the slope and reduce the stability of the slope.
