| Abstract: | 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. |
