Performance of rock-soil slope reinforcement and protection effect in cutting slope construction

Abstract

It is inevitable to excavate slide slope and damage rock slope under the rapid development of expressway. To further remedy ecological environment, correct understanding of side slope stability is essential for the effective reinforcement and protection of rock-soil slope. In this paper, the reinforcement and protection technologies of cutting slopes were introduced firstly, and then the classifications of rock-soil slope reinforcement technologies in China and abroad were compared. Taking the Daqing-Guangzhou Highway as the research subject, three kinds of reinforcement and protection schemes were proposed and analyzed. Combing fuzzy comprehensive judgment with analytic hierarchy process, a supporting model of cutting slopes was established. The analytic hierarchy process was used to determine the weight and the degree of membership was calculated. Finally, the model was applied into the project to carry out evaluation. The results showed that the fuzzy comprehensive evaluation model used in this paper had a good reference value for the future development of cutting slopes.
