摘　　要：用ANSYS-ADPL参数设计语言编制拱坝的计算命令流程序,参数化自动生成三维有限元的计算程序,建立计算的各边界条件(位移边界条件、温度边界条件、力的边界条件)宏文件、荷载文件,以及不同荷载组合的宏文件程序。通过编制多目标非线性规划及线性规划的数学模型应力变形及稳定、冷却费用等评价指标体系,得到封拱温度场多目标非线性优化结果,从而寻求对拱坝应力、稳定及冷却费用综合最优的拱坝体型和封拱温度场。ANSYS-ADPL language is used for compiling command stream program of arch dam; it will automatically generate a three-dimensional finite element computation program,and set up macro files of different boundary conditions (displacement boundary condition,stability boundary condition,and force boundary condition),load files,and macro files program with different load combination.By compiling a stress deformation,stability and cooling cost evaluation index system of multi -objective non-linear planning and linear planning mathematic model,a multi -objective non -linear optimization result of arch closing temperature field can be obtained so as to seek for an optimal dam type and arch closing temperature field in stress,stability and cooling cost.
