摘要
利用渗流场与温度场的相似性,运用大型的通用有限元软件ANSYS的热分析模块对渗流场进行仿真模拟计算。在计算过程中,通过ANSYS的APDL语言对模型进行编程计算,采用死活单元方法,运用自由面适应网格方法,从而计算出渗流相关物理量。为了验证计算结果的准确性,将相关结果与理论计算值进行比较,浸润线、渗流量和渗流场的数值都较为准确,结果表明ANSYS的热分析模块对均质土坝稳定渗流进行仿真模拟计算的可用性。
Owing to the similarity between the temperature field and seepage flow field, the large-scale general finite element software ANSYS acting as the platform, the computation of the stable seepage flow field is simulated by the ANSYS function of temperature field analysis. In this procedure, by applying the tool-APDL language, the element birth or death technique, and the Method of Water Free Surface Adapting Grid System, we calculate the corresponding magnitude of the seepage flow. A comparison between the numerical and theoretical results is made to confirm the accuracy of the results, by which the accuracy in numerical computation in seepage flux, seepage quantity and flow field is reflected. The result shows that it is feasible to apply the ANSYS function of temperature field analysis in the computation of the stable seepage flow of the homogeneous earth dam.
