摘 要: 基于ABAQUS软件平台,应用Python语言与ABAQUS子程序,对混凝土热学反演计算程序进行二次开发。其中,正演过程中包括的子程序有FILM,HETVAL和UEXTERNALDB,通过这3个子程序的扩展,实现正演计算;反演计算中应用Python语言开发微粒群反演算法。算例表明:该程序可用于混凝土反演分析,分析结果与试验数据对比较为吻合。
关 键 词: 水工结构;热学参数反演;微粒群算法;Python

Abstract: In this paper, the research is based on ABAQUS software platform with Python language and ABAQUS subroutines to develop concrete’s thermal inversion calculation procedures. Among them, the attributions process includes subroutines FILM, HETVAL, UEXTERNALDB. By the extension of these three subroutines, positive calculation is obtained But in inversion computation, Python language is applied to develop the particle swarm inversion algorithm. Instances show that the procedure can be used for concrete inversion analysis and the computational results are accordance to experimental data.
Key words: hydraulic structure; thermodynamic parameters inversion; particle swarm algorithm; Python
