在桥梁工程课程教学中,拱桥主拱圈和吊桥主缆的悬链线方程的推导是教学难点之一。在教材中,这两部分内容是在不同章节里逐一讲解,教学效果较差,而且缺乏对这两种悬链线方程的比较,学生难以理解。文章从拱桥和吊桥的受力特点出发,对这两种悬链线方程进行了推导和剖析,通过比较分析帮助学生深刻理解其内容,提高学生运用力学知识解决桥梁工程的实际问题,增强学习兴趣。

In the teaching of bridge engineering,the catenary equation deduction of the main arch circle of arch bridge and the main push-towing rope of suspension bridge is one of difficulty.This part of content is explained one by one in different chapter,is less effective,and lack of the comparison between the two catenary equations,student is hard to understand.With the stress characteristic of this two bridge types,the paper analyses the two catenary equations to help the students understand this part of content and improve the students＇ ability solving actual problem with mechanics knowledge of bridge engineering,strengthen learning interest.
