摘　　要：对于数值仿真模拟来说,数值模型的优劣直接关系到模拟结果的精度,为高效而准确的建立体型复杂的拱坝模型,基于APDL和UIDL两种语言在ANSYS中开发一种拱坝参数化建模子程序,系统介绍编制该子程序的步骤。并以南方某拱坝为例,分别采用建模子程序和仅利用APDL语言两种方法从前期建模到后期结果进行系统的对比分析。结果表明,两种方法所计算结果相近且均符合工程实际规律,其中采用建模子程序所建模型耗时更少且精度较高,从而印证了建模子程序的高效性与可靠性,同时为基于ANSYS的有限元二次开发在水工行业中的仿真模拟提供了借鉴和参考。For numerical simulation, the quality of the numerical model is directly related to the accuracy of the simulation results. In order to efficiently and accurately build a complex arch dam model, this paper developed an arch dam in ANSYS based on APDL and UIDL. Parametric modeling subroutine. The steps of compiling this subroutine are systematically introduced in the article. Taking an arch dam in the south as an example, a systematic comparative analysis was carried out using the modeling subroutines in this paper and the two methods using only the APDL language from the early modeling to the later results. The results show that the calculation results of the two methods are similar and They are all in line with the actual laws of engineering. Among them, the model built by the modeling subroutine in this article takes less time and has higher accuracy, which confirms the efficiency and reliability of the modeling subroutine developed by the author. It is also a finite element based on ANSYS. The simulation of secondary development in the hydraulic industry provides reference.
