关于风积砂地基扩展基础抗拔计算公式的探讨
摘要:利用风积砂地基抗拔室内模型试验资料,通过对抗拔土体破坏机理的全面分析,提出了土体形成极限承载力的三个受力过程,建立了扩展基础抗拔承载力计算的基本公式,与目前其它计算方法比较,成果精度提高很多倍,而且适用范围不受深宽比限制,便于推广应用。
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.
