(1) Grouting reinforcement: when the slope slope is broken and the joint cracks are developed and larger, the method of pressure grouting can be used to strengthen the slope slope, and the joint cracks cut around the borehole wall are soaked nearby, so as to cement the rock and soil of the broken slope and form the whole; In addition, the mortar column has the effect of bolting the rock and soil of the crushed slope, so as to improve the overall and stability of the slope. Grouting reinforcement provides deep reinforcement of slopes.

(2) Bolt reinforcement: When the slope slope is seriously broken, or the slope strata is fragile, a certain number of bolts can be driven into to strengthen the slope. The mechanism of bolt reinforcement of the slope is equivalent to the effect of bolts. Bolt reinforcement is a medium and shallow reinforcement method.

(3) Soil nail reinforcement: Regarding soft rock slopes or soil slopes, a sufficient number of soil nails can be driven into the slope body to strengthen the slope. The mechanism of soil nails reinforcing slopes is similar to the effect of group anchors. Compared with the bolt, soil nail reinforcement has the characteristics of "short" and "dense", which is a shallow slope reinforcement skill. The two are different in planning and accounting theory, but similar in construction technology.

　　(4) Prestressed anchor cable reinforcement: When the slope is high and the potential fracture surface of the slope body may be deep, the prestressed anchor cable is a better deep reinforcement method. Now, in the reinforcement of slope soil on both sides of mountain roads, the road slope Protective Net is gradually developing into a trend and is being accepted by an increasing number of people.

Slope protection net is a kind of rockfall protection net, which effectively improves the ecology of the slope, thereby inhibiting the further damage of the slope, thus forming a virtuous circle.
