Hydro-mechanical Analysis of Rainfall-lnduced Landslides 內容簡介
《降雨滑坡的水-力耦合分析（英文版）》分析了降雨入滲過程中降雨入滲與部分飽和土坡變形的耦合作用。利用極限平衡條件和部分飽和土的抗剪強度關系，建立了計算降雨入滲引起的無限部分飽和邊坡穩定性的解析解。解析解可以考慮耦合效應對邊坡穩定性的影響。討論了影響無限范圍部分飽和邊坡安全性的因素。研究了降雨對土質邊坡的滲流、空氣遷移、變形和穩定性的影響。濕潤鋒受孔隙空氣運移和土體變形的影響，結果表明，降雨入滲與變形的孔-機械耦合對非飽和邊坡的穩定性有重要影響。各向異性對孔隙水壓力的影響與非飽和土邊坡的深度和位置有關。
