Abstract

Abstract

According to the situations and the reasons of instability, the spray concrete with steel bar nets, preforced cables and cement grouting with high-pressure were adopted in the reinforcement design. Soil slope was also reinforced by mini-anti-sliding piles and cement grouting with middle-high pressure. A numerical calculation model was developed to analyze design parameters and materials properties. Using the model, the stability variations(displacement of side direction) of reinforcement structures and retaining wall, highway subgrade, soil slope as well as the axial force on the perforced cables and anti-sliding piles were analyzed. The analysis result shows the different types of reinforcement structure are integrated and formulated an organic entirety, and it is a very effective method to reinforce the unstable retaining wall.
