Abstract


With the increase the national basic building efforts in recent years , the rapid pace of highway construction , and a corresponding increase in the slope stability problems encountered by the highway side slope construction project . In the construction and operation of the process of high-grade highway slope , slope instability phenomenon but have occurred , and slope instability , which often have disastrous consequences . Therefore, the high-grade highways Slope Stability Analysis and Treatment Research , develop effective protective measures , has a very important theoretical and practical significance . Firstly, a wide range of topics related to research and depth based on a large number of domestic and foreign literature , slope stability analysis methods and computational theory of high-grade highways . On this basis , derived strictly meet the force and moment equilibrium conditions , slope slip surface shape and bars between the direction of the force and the role of point position at the same time do not make any assumptions about the slope stability generic slice method . In view of the complex slope stability analysis and critical slip surface search actually can be attributed to the solution of a multimodal containing highly non-linear programming problem , difficult to solve using traditional numerical optimization methods , this paper proposes using self-organization , the self-learning , adaptive and global convergence ability of genetic algorithm to solve the high-grade highway slope stability analysis . Second , the slope of the characteristics of the high-grade highways , comprehensively expounded the principle of Slope Treatment , prevention measures and technical points , propose appropriate Treatment Measures should be chosen for different geological conditions , and engineering monitoring system layout , monitoring the content and impact factors detailed introduction . Finally, the practice of the Hengping a highway the K28 work sites - slope engineering , finishing analysis, based on engineering various dynamic monitoring results contrast using genetic algorithms to calculate the slope stability factor , the slope using a variety of methods synthetical disposal there the results show that the method is practical and reliable , in accordance with the actual .
