摘　　要：在对各种抗拔理论的分析和室内模型试验的基础上,假定了抗拔土体的计算简图,推导出了扩展基础风积砂土体极限抗拔力的理论计算公式,与试验数据及其它抗拔理论(土重法、剪切法)计算结果作了对比,结果说明本文建立的公式是比较合理的.On the basis of the analysis of various uplift theories and indoor model tests,a calculation diagram of counter-uplift soil mass is presented,and a theoretical calculation formula is derived for the critical counter-uplift force of the aeolian sand soil mass.A comparison is made of the theoretical calculation results with test data and calculations based on other uplift theories (including the soil weight method and shearing method),which shows that the calculation formula proposed in this paper is more reasonable.
