| 摘 要： | 在动态形函数的基础上，提出了强夯动力计算机的动态有限元单元法，建立和推导了相关的有限元公式。该方法克服了以往一般有限元法计算强夯动力问题是无法考虑加固土质振动特性等缺点，能较实际地反映强夯加固的动力特性。

| Abstract: | Based on the concept of dynamic shape function,a finite dynamic element method(DEM) is developed for the compulation of dynamic consolidation.Formulas of the DEM are also derived.This method overcomes the shortcomings of conventional finite element methods,i.e.,the vibration characteristics of the soil to be consolidated cannot be considered.Therefore it reflects practically the dynamic characteristics of consolidation.The programs for the DEM are also compiled.Results of practical calculation show that the method is correct and feasible. |
