随着基于可靠度理论的结构设计方法的快速发展，可靠度理论已经成为土木工程专业学生需要掌握的重要知识。由于可靠度理论较为抽象、常涉及复杂的数值计算，学生常无法完成学习流程，导致学生学习兴趣匮乏，学习效果有待提高。针对上述难点，提出了一种基于计算可视化的教学方法。该教学方法基于EXCEL这一通用工具，可将各种可靠度算法的中间过程和结果进行直观分析和展示，消除可靠度理论学习中涉及的数值分析要求，由此精简学习流程。该方法可帮助学生从复杂的数值计算中解脱出来，将精力聚焦在可靠度分析原理上，方便和快速地理解和掌握相关知识点，并将所学知识其灵活应用于自己的研究领域。基于计算可视化的教学方法可大幅提高可靠度课程的学习效率和学习获得感，为土木工程可靠度理论的教学提供了一个行之有效的方法。

As structural design methods based on reliability theory develop rapidly, reliability theory has become an important knowledge for civil engineering students. Because the reliability theory seems to be abstract and complex due to the numerical algorithms involved, learning reliability theory has been a challenging task for students. In this paper, a teaching method based on visualization of computation is described, which is developed through the commonly available software EXCEL. With such a teaching method, different reliability algorithms which involve heavy numerical computations are implemented in EXCEL, where the intermediate results can be displayed explicitly and the programming requirements can be eliminated. As such, students can focus more on the concept and principles of the reliability theory, other than the tedious calculation details. The method of visualization of computation can significantly shorten the process of the learning for students, enhance the efficiency of learning, and improve the effectiveness of teaching. It provides a powerful tool for teaching reliability theory for civil engineering students, which has been considered challenging in the field.
