The practical experimental teaching is important to train civil engineering talents who should have project practice ability and innovation ability. Firstly, the paper analyzes the problems of civil engineering specialty experimental teaching: experiment teaching is attaching to theory teaching, experiment contents are outmoded and repeated, experimental teaching ways lack of novelty, examination scores are single and experiment content is unified. Then,this paper puts forward reforming measures of experimental teaching system: integrating the experiment item of existing theoretical course, establishing independent experimental course to experimental item which is independent from theoretical course, carrying out credit teaching in which examination score mainly depends on quantity and quality of experimental item to motivate students enthusiasm, transforming undergraduates’ scientific and technical innovation and teachers’ scientific project into experiment items, training students’ project practice ability and innovation ability.
