The graduation design is the most important link in undergraduate training process of civil engineering specialty, and its teaching quality directly determines the improvement degree of talents ability. Hence, based on investigating the graduation thesis of East China Institute of Technology, this paper finds out some problems and causes of the low level of the graduation design. As well, some measures are proposed to solve these existed problems to improve the students’ mechanics ability, innovation ability, thinking independently ability, engineering practical ability and so on. Practice proves thatreinforcing the mechanics teaching can improve the quality of graduation thesis.
