通过ADINA软件对挡土墙回填土进行了模拟，并运用生死单元对回填土进行了分层定义，从而得到了挡土墙在回填过程中不同时刻土压力情况，为挡土墙的设计提供理论依据。%The paper simulates the refilled soil of the retaining walls with ADINA software, undertakes the layering definition of the refilled soil with the birth-death elements, and concludes the pressure circumstances of the retaining walls in the refilling process at different periods, so as to provide some theoretical reference for the design of retaining walls.
