摘　　要：通过比较渗流场与温度场的相似性,论证了利用温度场模拟渗流场的可行性。对于给定的有限元计算模型,利用ANSYS中的APDL参数化语言完成对材料参数与属性的赋值。模拟出渗流场的渗透压及渗流速度的断面分布,根据模拟出的断面流量,计算出等效渗透率,并得出等效渗透率与孔隙率之间的关系。Based on the comparison between seepage flow field and temperature field in similarity, the feasibility of simulating seepage flow field by temperature field was discussed. For a given finite element model the material parameters and element properties were assigned using ANSYS APDL parameters design language. The distributions of seepage pressure and seepage velocity in the cross section were simulated. According to the simulated section flow, the equivalent permeability was calculated, and the relationship between equivalent permeability and porosity was drawn.
