  1. Considering the characters of bp neural network, such as the simple structure, the advisable malleability, self - fitness, self - studying, nonlinear function approximating, the considerable abilities of parallel computing, fault - tolerant and so on, the bp algorithm have been extensively applied to the areas of system modeling, pattern recognition and seismic exploration since 1986. compared with other algorithms, as the above reasons, the bp algorithm has become the most usual and efficient solutions to the artificial neural networks

    由於人工神經網路中的bp神經網路結構簡單,可塑性強,具有良好的自適應、自學習、極強的非線性逼近、大規模并行處理和容錯能等特點,自1986年rumelhart等人提出以來,被廣泛應用於系統建模、模識別、地震要領域。而bp演算法數學意義明確,步驟分明,是神經網路中最為常用、最有效、最活躍的一種方法。
  2. According to the geological data which was gained by exploration investigation, establishing a geological model which can reflect rock mass characteristics ; with analyzing the internal and exterior factors synthetically, the deformation and possible failure mechanism and mode of the cut slopes was confirmed which combines with stereoic projection and other techniques ; the stabilities of the 14 high slopes are estimated synthetically by applicable design codes and guidelines. with the estimate result and some other analysis methods, the rock mass mechanical parameters of slope are identified ; as a results, 14 high slopes fall into 4 categories based on rockmass characteristics and discontinuities. the stability and deformation of some typical slopes was analyzed with distinct element method by udec ; the safety factor of some dangerous slopes are calculated by rigid limiting equilibrium method for comparison

    首先著研究影響邊坡穩定性的內在因素,主要是通過地質、測量、現場觀測等手段取得研究區地質體的基礎地質資料,建立起能夠反映地質體結構特徵的地質模型;隨后綜合分析潛在的內外部影響因素,並結合赤平投影對邊坡可能的失穩模或破壞機製作出判斷;運用已有巖體質量分類方法對沿線14個高陡邊坡穩定性進行初步的評價,並結合試驗研究、經驗判斷、工程類比等手段確定了坡體的巖體學參數;根據穩定性初步評價結果將研究區14個高陡邊坡按開挖方分為4大類,並利用離散元程序udec對各類典型高陡邊坡進行了穩定性計算分析;對潛在危險邊坡利用剛體極限平衡法求出了不同工況下的安全系數。
