摘要
利用动态有限单元法建立和推导二维等参形式四边形动态有限单元，研究了沟埋式管与土的动力相互作用，求得管周土体的静、动应力分布．结果表明，动态有限元法比一般动力有限元法更精确、有效．
Based on the concept of the finite dynamic element method, a 2-dimensional isoparametric finite dynamic element is developed and then used to analyze the ditch conduit-soil dynamic interaction in this papar. We have got the result that distribution of static and dynamic stress along the outer preiphery of pipe. The results show that the present method is feasible and adaptable to practical engineering.
