摘　　要：采用传递矩阵方法对矩形地埋管道 -土共同作用问题进行了研究 ,通过对刚性矩形管道的共同作用分析与传统结构力学方法计算结果的对比 ,指出了在对刚性管道受力分析时应考虑土的约束作用 。Structural mechanics method (SMM) is usually used to analyze rigid pipeline and the interaction between soil and pipeline is ignored.Transfer matrix approach (TMA) is presented to study interaction between soil and buried box pipeline in this paper. The results of comparing TMA to SMM show that the soil constraint influence should be considered.The effects of the changes of model parameters on pipeline\|soil interaction are also discussed.
