The Study Of Expert Judgment System And Fuzzy Synthetically Judgment Of Rock Slope Stability

In recent years, with the increasing of the quantity and the scale of engineering construction, the disasters of rock slope failure take place frequently. The relevant loss also increases year by year. Therefore, it is more and more important to research the stabilization of rock slope. The amount of factors that influence the rock slope is quite large, how to fully consider the influence factors is the main problem that this paper studies.At first, the commonly used methods of evaluating rock slope stability in current engineering practice are compared and analyzed. The application and limitation of different methods are found and the advantage of this method over the others by fuzzy synthetically judgment is analyzed. Then the type of rock slope and the type of failure is detailed discussed, to find out the step of stability analysis and the sensitive factor, which can affect the stability of rock slope. Based on detailed geological investigation, hydro geological investigation and soil test, we can get the weight of each sensitive factor through the expert participating to evaluate, which use the fuzzy mathematics. Finally, we can get the evaluation result of the slope stability.Based on this theory, the expert judgment system is developed. The system is used to evaluate the slope of the factory and the slope of QingJiangGeHe Rock electricity station's water exporting hole. The result was reasonable. This method is strong on synthesis, effective, simple and can be used easily. It has a better consultative value for rock stability evaluation and slope treatment.
