摘要
针对目前深基坑工程现状,指出了目前基坑抗隆起稳定性计算方法的不足。采用滑缝法分析了土体抗剪强度低、基坑开挖深度大的深基坑抗隆起稳定性,建立了抗隆起稳定性计算模式,推导了适合于此类基坑抗隆起稳定性计算的公式,并分析了该稳定性计算式的适用范围,用工程实例将滑缝法与目前的计算方法进行了对比分析,取得了满意的结论。图6,表1,参10。
In view of the problem of deep foundation pits, the fall short of presently calculating method about basal heave stability is indicated. Deep basal heave stability which the excavation depth are relativity longer, the shear strength is relativity lower are studied by slip fissure method, and the model of deep basal heave stability is established. A formula for that foundation is proposed, and the scope of the formula is analyzed. The differences between slip fissure method and presently method is discussed using practice case. A satisfactory conclusion are gained. 6figs. ,1tab. ,10refs.
