According to the different setting positions of the hillside walls, the hillside walls are divided into road shoulder walls, road embankment walls, cutting walls, hillside walls and the like. The retaining wall which is arranged on the hillside and supports the soil body of the covering layer or the broken rock layer which possibly collapses on the hillside is called a hillside wall. The hillside wall has the characteristics of obvious restriction on construction and the like due to the fact that the requirements on the safety level of the building structure are high, the basic environment type is poor, the engineering earthquake-proof fortification intensity and the basic earthquake acceleration are high, and the requirements on the construction process are high.
The prestressed anchor cable is a rope-shaped bracket for anchoring the anchor cable in a rock mass by adopting a prestressing method and is used for reinforcing a side slope. The anchor rope is anchored into the rock body by the anchor head through the hole of the weak structural surface of the rock body, and the sliding body is connected with the stable rock stratum, so that the stress state of the slope rock body is changed, and the integrity and strength of the slope unstable rock body are improved. When the prestressed anchorage cable is constructed, special tensioning devices and machines are needed. Obviously, the prestressed anchor cable is a prestressed steel strand which passes through the sliding surface of the side slope in the stable rock body with the outer end fixed on the slope and the other end anchored in the sliding surface, and directly generates anti-sliding resistance on the sliding surface, so that the anti-sliding friction resistance is increased, and the structural surface is in a compressed state, so that the integrity of the rock body of the side slope is improved, the mechanical property of the rock body is fundamentally improved, the displacement of the rock body is effectively controlled, the stability of the rock body is promoted, and the aims of repairing the bedding, the landslide, dangerous rock and dangerous rock are fulfilled. The prestressed anchor cable has the good action and effect, and is widely applied to civil engineering, especially strong hillside construction.
