Abstract : based on analyzing the mechanism of fraction for anti - extraction soil by using the results of in - side model test about wind - borned sand deposit foundation, three stressing process of the ultimate bearing capacity in soil is given, and the basic formual for anti - extraction capacily calculation is established. compared with other methods at present, the accuracy of the calculation result is several times over that of others. because the scope of application isn ' t limited by width - to - depth ratio, it is very convenient for widely application
文摘:利用風積砂地基抗拔室內模型試驗資料，通過對抗拔土體破壞機理的全面分析，提出了土體形成極限承載力的三個受力過程，建立了擴展基礎抗拔承載力計算的基本公式，與目前其它計算方法比較，成果精度提高很多倍，而且適用范圍不受深寬比限制，便於推廣應用。 -
