RETRACTED ARTICLE: Instability of rock slope with different joints and multimedia politics teaching in plain area

Abstract

Multimedia technology is widely used in various fields around the world. In recent years, it has also entered teaching classrooms, expounding theories and opinions with its powerful information and sensory stimulation, enriching learning resources, affecting old learning models, and bringing new ideas. Due to a strong sense of time, current affairs and policy courses require multimedia technology to simplify teaching. Current affairs and politics class is an important part of political education. It integrates important current affairs at home and abroad, such as politics, economy, and culture, into the ideological and political theory of textbooks, and teaches them in the form of classroom activities. Moreover, this way of teaching can also stimulate students’ interest in learning to a certain extent. Correctly assessing the impact of rock thickness on the instability mechanism of bedding cliffs is an urgent problem for the mining industry. This article is based on early research and follows the technical route of “researched geological exploration, theory, and numerical simulation”. Based on the proper division of bedrock slope types, this paper systematically studies the influence of rock thickness on bedrock slopes and systematically studied the instability mechanism, failure process, and stability grade of three types of rock slopes. By creating a mechanical calculation model to derive the formula for calculating the stability, the completion of this work has a certain reference value for solving the problem of rock slope expansion in mining construction.
