摘　　要：沥青心墙坝堆石坝应用广泛,筑坝材料主要有沥青心墙、堆石、砂砾石等,材料的应力-应变关系为非线性关系。建立坝体的三维模型,采用分级加载方式模拟坝体填筑过程,使模型单元和材料性质随时间改变,较好地计算了坝体的应力和应变。Asphalt core rock-fill dam is widely used,its main materials include dam core,rubble,and gravel stone.The stress-strain shows nonlinear relationship.The establishment of three-dimensional model of the dam is in the process of simulate dam filling by the way of step loading,so that the model unit and the material properties can change with time,in this case,a better calculation of the stress and strain of the dam can be got.
