China accession to Washington Accord of the higher engineering education indicated the cultivation of higher education talent in civil engineering has gone into an internationalization substantive stage. As the practice of education reform of civil engineering multi-major graduation project in Chongqing University, it is not only to inspect the four-year core professional knowledge, ability and quality of civil engineering undergraduates, but also the ability of undergraduates facing to economic globalization, competition and teamwork. To enhance the quality of personnel training of multi-major Graduation Project, inspect the training objectives and teaching programs of each major, and improve the management of multi-major graduation project with evaluating of design quality and training model. According to the requirements for undergraduates of Washington Accord, quality evaluation mechanism of civil engineering multi-major graduation project has been established. It includes proof-vertification evaluation process, procedure-result evaluation process, evaluation standard of civil engineering multi-major graduation project and organization, in order to promote the combination of civil engineering multi-major graduation project and engineering practice effectively, and integrate the internationalization of civil engineering cultivation.
