摘　　要：本文介绍了分枝模态—二步分析法的原理,并以实际工程为背景,利用分枝模态—二步分析法,考虑桩土与卵形消化池结构的相互作用效应,通过建立两种计算模型:简化模型和标准模型,对卵形消化池进行了动力分析。同时,将分析结果与不考虑相互作用的情况进行对比,得出一些可供实际参考的结论。The principle of branehed mode-two step analysis method is introduced in this paper. Taking the actual project as the background, using branch modality-two step analytic method and considering the interaction effects of pile-soil and egg-shaped digester, the dynamical analysis of egg-shapped digester was carried on two calculating model named simplified model and standard model. At the meantime, the obtained analysis result has been contrasted with that of non-considering interaction. The reliable conclusions have been obtained.
