【摘要】 按梁———接头不连续模型首先通过对顶管管节和管节间的接头组建了刚度矩阵,并在此基础上进行有限元分析,通过实例分析得出的结果与实测值对比,可以看到基本相符合并且偏于保守,说明了理论分析的正确性。更多还原

【Abstract】 First, according to beam-joint non-continuous model the stiffness matrix for the pipe jacking tube couplings and joints among the tube couplings is constructed; moreover the finite element analysis is made based on this matrix. The results obtaining from example analysis are basically identical with the measured values. What’s more, the former is more conservative than the latter, which illustrates the correctness of theory analysis.更多还原
