Analysis And Application Of Soil Slope Stability Based On Grey Theory

At present, China is at rapid economic development and the western development period,70%of the total area of the country is land, plateaus and hills, many infrastructures related to slope governance. The actual slope stability and reasonable evaluation of the state, have a significant impact on the project success and people’s lives and property. Reasonably reliable for slope stability analysis and evaluation is very important.The topic of this thesis is to consider the application of grey theory to soil slope stability analysis, Slope engineering systems is considered to belong to the grey system category. Starting from the grey GM (1,1) modeling ideas, Introduces the basic principles, basic content and calculation methods of grey system theory. Application grey system theory to study the soil slope stability just starting out. Through displacement monitoring data of a slope which located at the Bi-Wei highway, establishment two GM (1,1) model which one is during the slope support, the other is after completion of slope support. The purpose of the model established to make the appropriate displacement prediction. Removing the inherent deficiencies. the model has high accuracy in a short time, the practical application of the model should pay attention to the establishment the grey metabolism model.Grey relational analysis of slope stability analysis has obvious advantages, it is also an important part grey theory. In analyzing the factors that affect slope stability, the stability of the factors that influence the degree of sequence on soil slope, the actual project can catch primary problems; propose targeted measures.Describes the theoretical requirements associated sequence of grey methods. Summarized the factors affecting slope stability generalize, and focus on the importance of a particular sequence factors with a detail slope project. Through the grey relational analysis reason of slope destabilization, put forward the corresponding engineering control measures. This article was first introduced grey correlation analysis of soil slope engineering analogy applied to15known slope as a reference, Deduced5study slope the stability steady or not. Prediction results compliance with actual.The results show that:it is appropriate and practical analysis soil slope stability in grey system theory, with high reliability. Modeling can effectively evaluate the grey slope steady state, have some ability to predict. Grey Theory can identify the slope stability influence factors sequence quickly and efficiently. Based on the existing slope data as a reference, use of grey relational engineering analogy evaluation can judge the the steady state of unknown slope.
