摘　　要：学生学习图乘法求解结构的位移时存在着很多难点,尤其是在具体的计算中缺乏正确的分析与计算过程。本文通过具体实例,分析了图乘法求解结构位移时的本质,阐述了图乘法根据叠加法原理求解结构位移的详细过程,解决了学生在求解结构位移时存在的困惑和容易出现的问题,从而使学生在使用图乘法时能有更加清晰的认识和更加准确的计算。There are many difficulties in solving the structural displacement by the graphic multiplication to the students,and especially there is no valid progress of the analysis and calculation in the actual calculations.In this paper,through specific examples,the essence of solving the structural displacement by the graphic multiplication is analyzed by the case-study,the whole process by the superposition method in solving the structural displacement by the graphic multiplication is stated,and the difficulties and the questions for the students in solving the structural displacement are solved,so that students can have a clearer understanding and more accurate calculation when using graph multiplication.
