The Stability Analysis Of Side Slope In Expressway And Its Research Of Treatment Technology

As the national capital in recent years greater efforts devoted to the rapid pace of highway construction, road construction and slope control in the face of rock and soil slope stability is also a corresponding increase. Slope in the high-grade highway construction and operation process, the slope instability phenomenon has occurred from time to time, and once slope instability, and its often disastrous consequences. Therefore, high-grade highway slope stability analysis and treatment technology research, development of effective protective measures, has a very important theoretical and practical significance of the project.In this paper, first of all to carry out a wide range of topics related to research, and based on a large number of domestic and foreign literature related to high-grade highway slope stability analysis method and theory in depth. On this basis, the export to meet the strict conditions of force and moment balance, sliding surface slope at the same time be the shape and direction and the role of inter-edge position does not make any assumption that the slope stability of general slice method. In view of the complexity of the slope stability analysis and search for critical slip surface can actually be attributed to a solution containing a high degree of multi-peak non-linear programming problems, using the traditional numerical optimization methods to solve difficult, for this paper, the use of self-organization, self - learning, adaptive capacity and the global convergence of genetic algorithm to solve the high-grade highway slope stability analysis. Secondly, the slope for the characteristics of high-grade highways and comprehensively expounded the principles of slope treatment, preventive measures and techniques proposed for different geological conditions should be the appropriate choice of treatment measures and monitoring system for slope engineering deployment, monitoring content and the impact of factors made a detailed presentation. Finally, a road K28 Hengping Slope Treatment Works Engineering Practice points, based on the analyzed results of the monitoring project, as compared with the genetic algorithm of the slope stability factor, the integrated treatment approach using a variety of the slope, the results show that the practical and reliable of the Act, in line with the actual works.
