  20. 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

    本文首先對順層邊坡層狀巖體及其中層理面和不連續面進行了分析,對其應力應變進行了研究,得出了順層邊坡性不僅與巖體中巖石強度有關,還與巖體中層理面及不連續面內聚力、內摩擦及其傾有關;論文建立了層理面和節理面地質力學模型,討論了其力學參數變化對邊坡穩影響,並在此基礎上將層理面和節理面歸納為順層邊坡穩結構面影響,同時討論了影響順層邊坡穩其他,從而得出順層邊坡穩評價預指標。
