Analysis of cutting slope reinforcement in swelling rock and soil

According to the unstable situation of an expressway cutting slope located in Zhengzhou city of China, four retaining regions were divided by reinforcement design and different reinforced structures were adopted in the four regions. Based on the design parameters of the reinforced structures and the natural mechanical properties of the rock cutting slope, the stability of the cutting slope after reinforcement was analyzed by numerical analysis. The result shows that besides the reinforced structures and the self-reinforced anchor bars perform high loading-capacity, the reinforced structures and the rock cutting slope have come into being a whole integer.
