作为一种新兴的教育现象和教育方式，“慕课”课程体系的研究尚处于初始的探索阶段。文章以土木类专业的通识性课程桥梁工程导论为例，开展了桥梁工程导论慕课课程建设框架研究，建立了包括课程内容、授课方式、互动方式和考核方式四方面的课程建设框架。研究表明：理论知识浅显化和教学方式富媒体的特点有助于课程的大范围推广使用；教学、互动和考核均包含线上和线下两个方面，将有助于发扬传统和新兴教育方式的优点，实现学生能力全面和均衡的发展。

As a rising education manor, the MOOC research is within the range of discovery. Taking introduction to bridge engineering as examples, the course construction frame is investigated including course contents, teaching manors, communication mode and assessment method. The investigation presents that such course is convenient to expand in much larger scales whose theoretical knowledge is more popular as well as teaching methods fall in scope of rich media. On-line and off-line teaching methods have been both included in the steps of teaching, interaction and testing. The teaching methods will be helpful to develop advantages of traditional and modern education methods, inducing comprehensive and balanced development of students' ability.
