本文提出一种研究上部结构-筏-桩-地基共同作用分析的新方法,尤其是筏基分析方法新颖,比之有限元方法优越。计算结果与实测数据有较好的一致性。利用本文方法可求得上部结构和桩土结点的反力,筏基中任意点的弯矩、扭矩、正应力和剪应力。本文对共同作用机理进行分析,得出了可供工程设计人员参考的有益结论,例如,抽桩分析,可期获得可观的经济效益。
This paper presents a new method for the analysis of the interaction between superstructures, piles, piles and foundations. In particular, the new method for analyzing sulfhydryl groups is superior to the finite element method. The calculated results are in good agreement with the measured data. By using this method, the reaction forces of the superstructure and the pile-soil node can be obtained, and the bending moment, torque, normal stress and shear stress at any point in the raft foundation can be obtained. This paper analyzes the mechanism of common action and draws useful conclusions that can be referenced by engineering designers. For example, analysis of pumping piles can obtain considerable economic benefits.
