Study On Slope Stability Evaluation System Using Case-based Reasoning And Optimization Design Of Anti-slide Structures

As one of the most important natural geological environments in the human existence and engineering actives, slope is affected by many uncertain and complicated factors, which makes the outcomes from traditional evaluation methods unsatisfactory. Slope engineering is usually based on experience, so it has great practical significance to study and utilize the experience of slope projects that have been made certain. Then it is advisable to set up an integrated intelligent evaluation and optimization treatment system based on available examples, which is of great academic significance and practical value for the stability evaluation and treatment in the slope engineering.Appropriate treatment measures should be taken to those slopes which have been proved to be instable. But as things stand here, the optimization design hasn't been attached enough importance to in most slope treatment design. So it makes much sense to study the design theory and application of the optimization.The paper is divided into two parts, which has a study on a whole system that includes slope stability evaluation to anti-slide pile optimization design. In the first part, a subsystem of CBR is studied by introducing it into the stability evaluation of a slope. And in the second part, optimization design in the slope treatment is further discussed, based on which an optimization-design model for anti-slide pile is set up, and then an optimization-design system is developed.The main contents present in this paper are as follows:(1) First, the purpose and significance of this paper is briefly expressed. And then, based on existing stability analysis methods of slope, actuality of slope treatment and optimization study on anti-slide pile, the research thinking and contents of this paper is put forward.(2) In part one, the basic theory and reasoning flow of CBR is introduced. Then case representation methods, case organization methods, case searching methods, similarity degree calculating methods and case adjusting study method are introduced respectively. The paper also discusses the representational and adjustment model, in which Access data-base is used to represent and storage slope cases. A new case retrieval model is established: First, the target factors weight of critical slope...
