Slope Stability Analysis And Evaluation

Combining with the research on the typical engineering slopes of the highway of Yuanjiang-Mohei, the slope disaster have comprehensively and systematically studied in 3 major domains, named foundations of geology, influence factors, analysis and evaluation of the stability with the mathematics tool of statistic, ANN and multianalysis regression. This text have systematic summarized the development characteristic, distribute law and stability control the factor of slope disaster, and set up practical slope stability evaluation method. This achievement can be used for guiding practices directly, and make some progress in the basic theory of the slope project and method research.Based on the slope data of the highway of Yuanjiang-Mohei, this thesis has made deeply analysis to the slope stability control of various kinds of factors, putted forward that the combination of structure has different control function on the slope formed from different rock qualities of weathering degree. A large amount of clay of slip zones data statistical analysis has pointed out groundwater function in the destroy process of the slope. The research of the activity faults shows its function of control to the slope stability.Statistical analyzed to a large number of data of high and angle of stability destroyed slope in slope stability evaluation, the paper come to a conclusion that the slope stability was controlled by the angle, and the angle has linear relevant relations compared with slope high. The rock integrality modulus (Kv) was taken into account for the first time in the ANN stability evaluation model of slope, has reached the better result. In additional, this thesis has set up the multianalysis regression model of slope stability evaluation, normalization method have adopted to deal with the data. These achievements deepen evaluation method research of slope stability.
