| The bedding rock slope's instability is one of the most important slope's instabilitiy, so it is necessary to lucubrate it. Based on synthesizing and analyzing the slope engineering studies all over the world, this thesis studies the bedding rock slope's stability and its forecast.At first it analyzes the bedding rock slope's bedded rock and its incontinuity face, and studies the stress, strain, stability's condition of the bedding rock slope, fully considering the cohesive force of rock layer and incontinuity face.Geologic mechanics models of two types of bedding rock slope are set up, the instability coefficient of bedding rock slope under different mechanical parameters is computed, and the conclusion that the stability of bedding rock slope is relation to rock layerer, cohesive force of incontinuity face, inner friction angle and rock layer obliquity has been gotten.Based on the above discussion, the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face's influence factors, and discusses other factors that influence the bedding rock slope's stability, so gains the evaluating and forecasting index marks.At last, the FNN is used for forecasting bedding rock slope's stability, and the FNN's bedding rock slope forecasting system is set up which is successfully applied in WanLiang speedway slope engineers. |
