摘要由於地質因素的不確定性,高邊坡工程復雜性和錨固工程的特殊性,待邊坡開挖揭示后,根據邊坡的實際地層巖性,風化程度、破碎程度、構造裂面、坡體結構和含水狀態等因素,綜合校核和分析判斷是否實際,對高邊坡防護加固進行動態設計,確保坡體穩定結構安全。As the tension fractures exist, spread and deep weathering is strong, which causes the lowing of the strength of the engineering slope

本文討論了含裂隙介質地下水污染物輸運與生物降解非線性方程組數值求解方法.方程含有對流項、擴散項、生長、死亡、吸附、解吸、趨化和孔隙與裂隙介質界面間的交換項的非線性偶合,使演算法十分困難.本文討論了無生化過程時的幾種求解方法,數值結果表明:用三次迎風插值法對常見的對流項占優勢,且場變量有較大梯度的問題較適用.在討論有生化反應過程時,利用對流項與生化反應項的特徵時間量級估算,給出了求生化過程作用子步的時間步長估算辦法.用上述方法所得到的模擬結果與解析解、無化學反應和有化學反應的實測值對比,吻合很好分享友人
