【摘要】 间接荷载作用下梁的内力影响线在实际工程中有广泛的应用。然而，一般教材都是先给结论再证明，这导致很多学生在刚开始接触影响线时不能够深刻理解。本文采用静力法从3个不同的角度求解了间接荷载作用下梁的内力影响线，这3种求解思路是对一般教材求解间接荷载作用下梁的内力影响线的一个补充和阐释。本文的求解思路直接明了，在教学实践中可以帮助学生更多元地理解相关内容。更多还原

【Abstract】 The influence line of internal force of beam under indirect load is widely used in practical engineering. However, general textbooks are based on the idea of giving the conclusion first and then proving it, which leads to the inability of many students to have a deep understanding of influence line at the beginning. In this paper, the static method is used to solve the influence line of internal force of beam under indirect load from three different angles. These three solutions are a supplement and explanation to general textbooks to solve the influence line of internal force of beam under the indirect load. The solution ideas are straightforward and clear, which can help students to understand the relevant content more diversely in teaching practice.更多还原
